CURRENT RESEARCH INTERESTS:
(i) Atomic structure of surfaces, surface modification by ion
irradiation.
(ii) Interface structure and roughness.
(iii)Multilayers and their ion beam modification
(iv) Epitaxial layers and Self-assembled epitaxial growth (MBE growth, Quantum dots, Single-electron tunneling)
(v) Defects in epitaxial layers and at their interfaces.
For
these studies we use Rutherford backscattering spectrometry
and channeling techniques
with MeV ions from our 3MV Pelletron accelerator , X-ray reflectometry
and X-ray standing wave techniques
with MoK_alpha_1 X-rays from an 18 KW rotating anode
X-ray source and 200 keV TEM. Besides these
facilities in our laboratory we use other techniques
like, EDX, SEM, XPS, SIMS etc.
available elsewhere in the country and synchrotron radiation
sources abroad.
We grow epitaxial layers
and self-assembled epitaxial structures by molecular beam epitaxy (MBE).
In-situ characterizations are
done by reflection high energy electron diffraction (RHEED) and scanning
tunneling microscopy (STM) and
scanning tunneling spectroscopy (STS) with a variable temperature
scanning tunneling microscope
(VTSTM, Omicron) operating under ultrahigh vacuum (UHV) condition .
The VTSTM is connected with the
MBE system.
INTERNATIONAL COLLABORATIONS (as principal investigator):
(i) Indo-German bilateral collaboration with
Prof. G.Materlik, HASYLAB at DESY, Hamburg, Germany.
(ii) Indo-US collaboration with Prof. T.P.Das and Prof. W.M.Gibson,
State University of New York at Albany,
New York, U.S.A. and Dr. B.Rath,
Naval Research Lab, Washington D.C., U.S.A.
