Summary of Research Work
Possess more than thirty two years of experience of research and development in the field of Photon and particle induced X-ray physics, electronic instrumentation, Solid state material characterisation and experimental physics. The specific areas of interest are photon induced atomic inner-shell vacancy creation and de-excitation processes; characterisation of Solid state materials using optical methods, Deep level transient spectroscopy, C-V, C-T measurements and carrier life time measurements; Processing of electronic materials like GaAs, Si, hydrogenated a:Si and MCT and the Surface passivation using anodic oxidation. Designed and Developed indigenous instrumentation needed for all above types of experimental work.
In the area of X-ray spectroscopy the energy dispersive measurements on the photon induced atomic-inner-shell vacancies and fluorescent X-rays have been made. The parameters like differential and total X-ray production cross-sections, relative x-ray peak intensities; sub-shell radiative decay rates; fluorescence yields of LIII sub-shell /M-shell are measured .The angular distribution of fluorescent X-rays to investigate their anisotropy have also been measured. The measurements of above parameters are of great importance on account of their numerous applications in the fields of radiation physics, atomic physics, nuclear physics, solid state physics, plasma physics, astrophysics and non-destructive testing of samples of biological, geological, archaeological and technological interests.
The atomic beam line experiments were setup at Nuclear Science Centre (Now IUAC) at new Delhi, the light ion beam room (LIBR) chamber was been designed to use the Si(Li) detector and to improve the solid angle of detection, reduce the absorption of radiation in the path. For this a specially designed chamber with changeable polypropylene window and Aluminium collimator was fabricated. This has made variety of experiments feasible in the area of Atomic Physics using low energy x-ray and photon detectors.
The single wire gas flow proportional detectors were designed, fabricated and calibrated for alpha particles as well as x-rays for position sensitivity and resolution. These detectors have shown the resolution of better than 19% at 5.9 keV photon energy and the position sensitivity of 0.4 mm. These characteristics are comparable with the commercially available detectors. Optical communication systems, WDM and its applications and enhancement of bandwidth of optical communication systems. Fabrication, simulation and characterisation of nanostructures.
Designed and developed several scientific instruments and tools for experimental research in life science, physical science and environmental sciences and biotechnology for the researchers of these schools. The research includes the interdisciplinary work in the areas of solar energy, environmental science and biological sciences. From 2005 to 2009 setup a state of art analytical instrumentation facility AIRF at JNU as its founder Director. The facility is of its own kind in India that houses more than 25 highly sophisticated scientific analytical equipment at one place.
The areas of my current research interests include characterization of materials using XRF, SEM and XRD, investigation of atomic and radiative processes, Investigation of properties of solar materials, synthesis and characterisation of nanoparticles and theoretical studies of their properties for solar cell applications. MXenes and their applications as electrode materials for supercapacitors and energy storage devices. Synthesis and characterization of Graphene, Cu2O and CuO, ZnO, Sn2O and Barium titanate and Potassium titanate nano-structures.

AN OVERVIEW OF RESEARCH WORK
EXPERIMENTAL APPROACH
My thirty years of experience of research and development has been in the field of electronic and mechanical instrumentation, electronic material characterization and experimental physics. The specific work includes research on photon induced atomic inner-shell vacancy creation and de-excitation processes, characterization of materials using x-ray, gamma ray and optical methods, deep level transient spectroscopy (DLTS), C-V, C-T measurements and carrier life time measurements; Processing and characterization of electronic materials such as GaAs, Si, Ge, SiO2 films and MCT and their Surface passivation using anodic oxidation. Design and development of position sensitive radiation detector for x-ray and alpha particle detection. Design and development of a low cost multipurpose videoscope of clinical examinations under CSIR research project. Measurement and study of iron induced epileptic behavior in rat brain. And the development of indigenous instrumentation needed for all above types of work.
PHOTON –INDUCED ATOMIC INNER-SHELL X-RAYS:
The experimental measurements on the photon induced atomic-inner-shell vacancies and emitted fluorescent X-rays have been made. The parameters like differential and total X-ray production cross-sections, relative x-ray peak intensities; sub-shell radiative decay rates; fluorescence yields of LIII sub-shell /M-shell are measured .The angular distribution of fluorescent X-rays to investigate their anisotropy have also been measured. The measurements of above parameters are of great importance on account of their numerous applications in the fields of radiation physics, atomic physics, nuclear physics, solid state physics, plasma physics, astrophysics and non-destructive testing of samples of biological, geological, archaeological and technological interests. The topic wise description of above work are as under.
X-RAY PRODUCTION CROSS-SECTIONS
The partial L-shell x-ray production cross-sections with ~59.57 keV photon excitation are measured in elements with atomic number 73 Z 92. The measurements have been made in a 90 reflection geometry with 241Am as source of 59.57 keV gamma rays. The measured cross-sections are also compared with the theoretical calculations in the form of relative intensities I(L )/I(L), I(L )/I(L ) and I(L )/I(L ). The results have been interpreted in terms of photo-ionisation cross-sections, fluorescence yields, Coster-Kronig transition probabilities and radiative decay rates.
ENERGY DEPENDENCE OF L-SHELL X-RAY RELATIVE INTENSITIES
The energy dependence of L shell x-ray relative intensities of some high 'Z' elements has also been investigated in the photon energy region of 14 E 44 keV. The external conversion K x-rays of elements in the region 37 Z 64 induced by 60 keV photons from 1 curie 241Am source in a double reflection geometry. The results of such measurements are compared with the calculated values using the sub-shell photo-ionisation cross-sections, fluorescence yield and radiative and non-radiative decay rates. It has been established from above results that unlike K shell, the L shell relative intensities are not independent of photon energy.
THE LIII SUB-SHELL DECAY RATES
The LIII sub-shell relative radiative decay rates in Pb Th and U by selective ionisation of LIII sub-shell are also measured. The technique of selective ionisation using radioactive sources has been used for the first time to determine above decay rates. As no other experimental data for LIII sub-shell radiative decay rates are available, the measured values are only compared with the theoretical values and found to show a good agreement.
ANISOTROPY OF PHOTON INDUCED X-RAYS
The experiments are carried out to investigate the theoretical prediction of Flugge et al (1972)about the anisotropic emission of radiation from the states with J1/2 .The measurements of sub-shell relative intensities of resolved peaks are made at emission angle varying from 60o to 150o at 10o intervals. The above measurements have revealed for the first time that x-rays originating from the states J1/2 (e.g.LIII sub-shell J=3/2) and falling under L and L peaks show an anisotropic angular distribution. However, the peak L and L do not show any measurable anisotropy.
These results, though in conformity with the predictions of Flugge et al (1972) cannot be compared with other results as no other experimental or theoretical data are available.
M –SHELL FLOURESCENT YIELDS
The average M shell fluorescence yields have also been measured for some high 'Z' elements. The M-Shell vacancies are produced by photo ionisation with 5.597 keV Mn X-rays emitted from 55Fe radioactive source. The values of measured M-shell x-ray production cross-sections are used to determine using the theoretical values of M-shell photo ionisation cross-sections from Scofield (1973). The results are compared with other data wherever available and in some cases the calculations for are made from the available theoretical data. It is also observed that the average fluorescence yields are independent of initial vacancy distribution among its sub-shells.
CHARACTERISATION OF SEMICONDUCTORS MATERIALS:
The research work related to the characterisation of semiconductor electronic materials has been conducted at, Solid State Physics Laboratories, Ministry of Defence, Delhi - 110054. During my stay there the work was done in the following areas. (Most of which is classified)
MINORITY CARRIER LIFETIME MEASUREMENTS
The minority carrier life time measurements were performed in wide range of semiconductor materials like Germanium, Silicon, Gallium Arsenide, Cadmium Telluride and Mercury Cadmium Telluride. The photo-conductive decay method was used for the preliminary characterisation of the solid state electronic materials developed at the laboratory. The electronic and mechanical equipment was set up for above purpose and several types of measurements were made.
FOURIER TRANSFORM UV-VIS-IR SPECTROSCOPY
The characterisation of above mentioned materials was also carried out using Fourier Transform Spectrometer in UV, visible and IR regions. The materials were tested for their transmittance in the specific wavelength regions of interest. This characterisation was routinely done for the samples developed in the laboratory. The BioRad digital FT-Spectrometer was used for these investigations. The use of Carry-14 spectrometer was also made for some measurements.
CV-CT MEASUREMENTS
The C-V, C-T measurements were made in various types of semiconductor materials like Si, Ge, GaAs, CdTe, HgCdTe etc. for their characterisation. The samples of the materials grown in the laboratory by different processes like LPE, VPE, MBE, & MOCVD etc. by other working groups, were generally characterised. The MOS structures were prepared on the material surfaces after etching, polishing and cleaning by standard processes. The oxide coatings of known thickness were deposited and aluminium, indium, silver or gold gate contacts were deposited using vacuum evaporation. The schematic study of samples for C-V and C-T measurements was carried out over a wide temperature range from 77oK to 400oK. These measurements were made on BioRad DL-4600 system with built-in cryostat temperature controller and C-V, C-T measurement facility at 1 MHz frequency. The results have been used in classified defence projects.
DEEP LEVEL TRANSIENT SPECTROSCOPY
The deep level impurities \ traps play very important role in determining the suitability of material and the device performance. The characterisation of these defects thus assumes great significance in material development. The one of the techniques to do so is by means of deep level transient spectroscopy which offers various advantages over the other
available techniques. The EL2 defects in GaAs were (in particular) investigated for the GaAs ingots developed at Solid State Physics Lab. The material samples were prepared in the form of MOS structures and were investigated for deep level defects by BioRad DL-4600 DLTS unit. The samples of GaAs, Si, Ge and MCT were studied. The devices in the form of diodes, LED, solar cells etc. were also used as samples to characterise the deep traps.
PASSIVATION OF MCT
The MCT wafers were characterised for their suitability for fabrication of IR detector devices like linear arrays and CCDs. For this purpose the raw MCT crystals grown in the lab. were processed and MOS structures were fabricated after growing an oxide film (100 - 500 A degree thick) by anodic oxidation process. The gate structures were grown by vacuum evaporation of In, Ag, Al and Au and the passivated MCT wafers were characterised for their suitability for making IR devices.
CHARACTERISATION OF a-Si:H SOLAR CELLS
The hydrogenated amorphous silicon solar cells were characterised by CV,CT and DLTS methods for their intrinsic properties and their performances before and after annealing. The MOS structures using SiO2 film were used for the characterisation.
ION-INDUCED ATOMIC INNER-SHELL PROCESSES
The availability of high energy ion beams from a 15-UD Pelletron at Nuclear Science Centre (IUAC) is being used for some experimental investigations of atomic inner-shell excitation and de-excitation processes. The investigations of K, L, and M-shell ionisation by heavy ion beams and the related processes like x-ray production, REC, RTE and molecular orbital formation are under way. The following experiments have already been performed.
STUDY OF GOLD L X-RAYS IN Ni-Au
The production of L shell x-rays of gold from thin targets 20 gm/mg with 58-87 MeV Ni+5ion bombardment has been studied. The experimental chamber was modified to increase the detector - target solid angle considerably and to reduce the path between detector window and target. The well collimated detector gives very pure L x-ray spectrum free from background noise. Among the interesting features observed in the experiment are the peak height shift and the re-arrangements of intensity distribution among resolved peaks of X-rays. The estimate of multiple vacancy creation in some sub-shells of L shell has been made. The energy dependence of relative L shell X-ray intensities and absolute X-ray production cross-sections are also measured and compared with theory/other data wherever available.
STUDY OF K X-RAYS IN Cu-Cu SYSTEM
The production of K shell X-rays in Cu-Cu system at high projectile energy and charge state has been investigated. The symmetric molecular orbital effects and some interesting results have been observed. The charge state dependence of molecular orbital formation has also been explored.
DESIGN AND FABRICATION OF X-RAY DETECTION CHAMBER AT NUCLEAR SCIENCE CENTRE
The light ion beam room (LIBR) chamber at NSC has been modified to insert the Si(Li) detector to improve the solid angle of detection and to reduce the absorption of radiation in the path. This has been done by designing a flange with changeable polypropylene window and Aluminium collimator. A variety of experiments have now therefore become feasible at NSC in the area of Atomic Physics using low energy x-ray and photon detectors.
DESIGN AND DEVELOPMENT OF GAS FLOW POSITION SENSITIVE DETECTOR
The low cost, single wire gas flow proportional detectors have been designed , fabricated and tested for alpha particles as well as x-rays for their performance of position sensitivity and resolution. These detectors have shown the resolution of better than 19% at 5.9 keV photon energy and the position sensitivity of 0.4 mm. These characteristics are comparable with the commercially available detectors. The efforts to further improve upon these characteristics are on.
MOLECULAR ORBITAL FORMATION AND MO X-RAY EMISSION IN ION ATOM COLLISIONS
The molecular orbital K- shell x-rays were studied from the ion excited atom of copper in the copper-copper system. The copper ions with various charge states were obtained from the Pelletron at Nuclear Science Centre
CALIBRATION AND OTHER PROPERTIES OF SOLID STATE DETECTORS
The gas flow position sensitive detector designed and fabricated at JNU is further being improved to provide indigenous substitute. The prototypes were fabricated at USIC JNU and were installed and tested at Nuclear Science Centre New Delhi. The performance of the detector has been evaluated in real working conditions and the characteristics were found to be near desirable.
