Having more than two decades of experiences in teaching at undergraduate and postgraduate levels and research, my specified task is to foster excellence in teaching, learning and research within the framework of the education system of a university. In general, my goal is to produce highly acclaimed science graduates with both strong base of Physics and the complementary skills needed to be a successful researcher or teaching professional. I always prefer interactive teaching. My main research interests are in Condensed Matter Physics and Materials Science. I conduct experimental research on the development of thin solid films and nanostructured materials based on new compounds whose constituent elements are earth abundant and exhibit favourable optical and electrical properties for photovoltaic device (solar cell and photodetector) applications. During my Ph.D. (1988-1993) and Post Doctoral (1993-1996) work at IIT, Kharagpur I had been trained and motivated towards the search and development of new and potential materials for industrial uses. Many major research projects funded by DST, CSIR and UGC have been completed successfully. I am striving to build up a nationally competitive research laboratory here at the department of Physics.
- 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 more than 40 research articles in the journals of international repute. I have also completed three major research projects funded by DST, Government of India and CSIR, New Delhi and UGC.
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 Condensed Matter Physics, electrodynamics, Mathematical Physics 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 (Awarded)
I am interested in supervising post graduate students in the area of experimental condensed matter physics and materials science, mainly to develop nanostructured materials and thin films. I am well capable of handling various sophisticated and modern analytical instruments in the laboratory.
