Hello! I'm Arnab welcome you to my personal website....
I am an experimental condensed matter physicist. I did my Ph.D. from Institute of Physics, Bhubaneswar under the guidance of Prof. P. V. Satyam on growth, characterization and multifaceted applications of various oxide semiconductors and their heterostructures with noble metals. I have spent two years at Physics department, IIT Kharagpur as Postdoctoral research fellow, where I have worked on inorganic/organic 2D van der waals materials growth and optoelectronic applications (Photodetectors, LEDs and Solar Cells). Then I moved to Faculty of Engineering, Bar Ilan University, ISRAEL as a PBC Postdoctoral fellow, where my research was focused on electronic and optoelectronic devices (FET based Photodetectors and LEDs) based on graphene and beyond. After that I worked at Physics department, Yonsei University, KOREA as research professor focusing on CVD growth of 2D TMDCs and in-situ TEM/STEM studies under the influence of external stimuli like temperature, voltage, pressure, gases etc..At the beginning of 2020 on 2nd January I have joined Physics Department, Belda College (Affiliated to Vidyasagar University) as Assistant Professor, here I have been mainly involved in teaching graduate (B. Sc. Hons.) and post-graduate (M. Sc.) courses running in the Physics department..and partially doing my research in collaboration with my previous supervisors at IIT Kharagpur (India), Institute of Physics Bhubaneswar (India) and Yonsei University, Korea.
