MOTIVE / FIELD OF RESEARCH:
Study of Swift Heavy Ion Irradiation Induced Effects
in Semiconductor Materials and Devices:
1. Irradiation with
energetic ions (1MeV-3MeV & 100MeV-150MeV)
2. Characterization
by I-V, C-V, TSCAP, TSC, DLTS, IR, XRD, Glancing Angle XRD,
XPS, AFM,SEM with EDAX,
TEM, UV-Visible Absorption
Spectroscopy, Temperature Dependent Four Probe Resistivity Measurements
and
RBS.
3. Fabrication of Metal/Semiconductor
Junction Devices and their Characterization
RESEARCH EXPERIENCE:
Working since March 1996 in the general area of SEMICONDUCTOR
PHYSICS with the specific aim of SURFACE MORPHOLOGICAL as well as INTERFACIAL
STUDIES of Swift Heavy Ion Irradiation Induced Effects on compound as well
as elemental semiconductors using different characterization techniques.
Moreover, I have also hands on experience for synthesis and characterization
of semiconductor nano-particles. During my stay at IUC, I was actively engaged
in operation and maintenance of ESCA Machine along with the data (AES, XPS,
UPS) analysis for in-house publications as well as external users from different
universities/institutions. Moreover, during operation and maintenance of
ESCA machine, I have also hands on experience for UHV systems. Here I am
pursuing energetic ions (1-3MeV and 100-150MeV) induced near surface modifications
in semiconductor materials as a function of irradiation temperature, angle
of incident and charge state of projectile ions. Hands on experience for
following techniques: Electronic Flow Characterization techniques: Current-Voltage
Measurement (I-V), Capacitance-Voltage Measurement (C-V), Thermally Stimulated
Capacitance (TSCAP), and Thermally Stimulated Current (TSC). Surface morphological
techniques: Atomic Force Microscopy (AFM) and Scanning Electron Microscopy
(SEM), Transmission Electron Microscopy (TEM) Chemical Analysis techniques:
X-ray Photoelectron Spectroscopy (XPS), Ultra-Violet Photoelectron spectroscopy
(UPS), EDAX, and Secondary Ions Mass Spectroscopy (SIMS). Structural Analysis
techniques: X-Ray Diffraction (XRD), Infra-Red Spectroscopy (IR), UV - Visible
Absorption Spectroscopy.
