Samit Kumar Ray

Biography

Born on 1961, Prof. Ray obtained his M.Sc., Physics (1982), M.Tech., Materials Science (1984) and Ph.D. (1991) from IIT Kharagpur. He worked as a Scientist-B for a brief stint in 1984-85 at Solid State Physics Laboratory, Delhi. He joined IIT Kharagpur as a Lecturer in 1991 and rose to the position of Full Professor in 2004 and Professor (HAG) in 2010. He has served as the Head of the Department of Physics (2011-2014), founder Head of the School of Nanoscience and Technology (2014-2016) and Dean, Postgraduate Studies and Research (2015 – 2016) at IIT Kharagpur.

Research Interest

broad area of experimental condensed matter physics focusses on semiconductor nanostructures, epitaxial growth of quantum structures, nanophotonics and physics of nanodevices. His research has run the gamut from very practical fields such as pseudomorphic strained SiGe/SiGeC alloy heterostructures for high mobility MOSFETs to low dimensional quantum structures. His studies on Ge quantum dots and strained Ge to achieve light emission from an indirect bandgap semiconductor are useful to realize Si based lasers in future. His research results on floating-gate flash memory, quantum dot infrared photodetectors and nanowire heterojunctions are considered as significant breakthroughs for future nanodevice applications. Prof. Ray has supervised twenty three Ph.D. students (another twelve continuing at IIT Kharagpur) and more than fifty dissertations in UG and PG levels. He has completed 16 sponsored research projects worth over Rs. 18 crore as a PI/Co-PI
