Dr. Subhashis Das is working as a research associate in Institute for Nanoscience and Engineering, University of Arkansas, Fayetteville. Previously, he worked as assistant professor in the department of Electronics and Communication Engineering, Brainware University, Kolkata. He has worked as a Senior Technical Consultant in Accurion Scientific Instrument Pvt. Ltd. He successfully completed his tenure as a National Post-Doctoral Fellow at Indian Institute of Technology Mandi. Before that, he completed his Ph. D. in Semiconductor Devices from Indian Institute of Technology Kharagpur. His current research interests include hetero-epitaxial growth of Group IV and III-V compound semiconductors (AlGaN/GaN, InGaN/GaN, AlGaAs/GaAs, InGaAs/GaAs, GeSn etc), high end characterization of layered single crystalline heterostructure for high speed switching device and chemical sensing applications. He is also interested in two-dimensional Chalcogenides for device and sensing applications. During his tenure in IIT Mandi, he synthesized very much new and interesting 2D TMD for gas sensors and MOSFETs.
