Professor ,Dean of Faculty of Natural and Mathematical Sciences
My main research interest is closely related to do experiment in the field of condensed matter physics and materials science. My ultimate aim is to develop new materials for photonic device applications. At present, my interest is to teach all branches of physics at the undergraduate level and condensed matter physics or related subjects at the post graduate level. I did M.Sc. (Physics) with solid state physics specialization (1987) and Ph.D (1993) in experimental solid state physics and materials science: "on the growth and characterization of thin films of Zinc/cadmium- phosphide based compound semiconductors".
- M.Sc.(5 year integrated) Physics (IIT, Kharagpur, 1987)
- Ph.D. (Materials Science, IIT, Kharagpur, 1993)
I did my graduation from the Department of Physics, IIT Kharagpur and Ph.D. from Materials Science Center from the same Institute (IIT). My Ph.D work was on the preparation and characterization of thin films of II3-V2 group compound semiconductors for photovoltaic devices and solid state lasers. I had started my teaching carrier in 1996 as a Lecturer of Physics at the North Eastern Regional Institute of Science & Technology, Itanagar, AP before I was joined in the West Bengal Educational Service in the year 1997. My main research activities include the synthesis and characterization of various types of advanced electronic materials namely, compound (binary & ternary) semiconductors, diamond-like carbon (DLC) films, nanostructured germanium material for light source & flash memory devices, nanocrystalline zinc oxide (ZnO), organic-inorganic hybrid nanocomposites and related materials at the nanoscale for photonic device applications. I have published nearly 30 research articles in the journals of international repute. I have also completed two major research projects funded by DST, Government of India and CSIR, New Delhi. Presently I am supervising in a UGC sponsored research project on the development of Zinc-Tin-Phosphide semiconductor thin film and single crystal for solar cell applications.
Research / Administrative Experience+
My present research is primarily based on the growth of various materials like, Ge nanocrystals, zinc oxide nanocrystals, zinc-tin-phosphide chalcopyrites thin polycrystalline films using ionized cluster beam deposition (ICBD) techniques and studying of their structural, electrical & optical properties.

Teaching / Other Experience+
I am keenly interested to teach all branches of physics at the undergraduate level and solid state physics/condensed matter physics, electrodynamics or related subjects at the post graduate level. I also conducts general and advance laboratory classes at the undergraduate and postgraduate levels.
Post Graduate Supervision+
Name of the Ph.D students (JRF) working under my supervision:
1. Tamaghna Maitra (UGC Fellow)
2. Sukhendu Mukherjee (UGC Project Fellow)
3. Banasree Sadhukhan
I am interested in supervising post graduate students in the area of experimental condensed matter physics and materials science, mainly to develop nanostructured materials. I am well capable of handling various sophisticated and modern analytical instruments in the laboratory.
