Dr. Chandan Bera
Scientist-E/Associate Professor
Dr. Chandan Bera joined as a scientist at the Institute of Nano Science and Technology Mohali in May-2014. He received his M.Sc degree from the Indian Institute of Technology Bombay in 2007, and he worked in CEA-Grenoble and Ecole Centrale Paris during his Ph.D. degree and received his Ph.D. in October 2010. Currently, he is working on the thermal and electron transport mechanism in nanostructured materials and developing a simple predictive model for thermal and electron transport in low-dimensional and nanostructure materials to design thermoelectric devices efficiently. His group is also interested in electron and spin transport properties in heterostructures interface and working on the electronic and spintronic properties of the interface from the atomistic calculation based on density functional theory (DFT). Other research interests of the group are Piezoelectricity, Hydrogen generation for clean energy. **************************************************************************************************************************************** "One N-PDF and one JRF position are available in our group in computational nanoscience. The candidate with a Ph.D. degree in physics/chemistry/material science can send his/her CV. For the JRF position, candidates with CSIR/UGC fellowships can apply. "

Dr. Chandan Bera group performed theoretical calculation and studied low temperature thermoelectric properties of CoSbS with the effect of including spin-orbit coupling (SOC) interaction. The electrical properties calculation with SOC and 0.5μB atomistic magnetic moment on Co atoms shows a metal-like behavior due to a strong effect of spin-orbit coupling and a larger shift of VBM towards CBM leading to closure of the energy band gap. They have shown that a 10^7 times increase in power factor is possible by increasing magnetic field. This work calls for further investigation of electrical properties of CosbS at low temperature.
