Scientist-D/Assistant Professor
Dr. Chandan Bera joined as scientist in the Institute of Nano Science and Technology, Mohali on May-2014. He received his M.Sc degree from Indian Institute of Technology, Bombay in 2007 and he worked in CEA-Grenoble and Ecole Centrale Paris during his PhD degree and recvied his PhD on October-2010. During his PhD, Dr. Bera with collaboration Dr. Natalio Mingo, CEA- Grenoble, and Dr. Sebastian Volz, Ecole Centrale Paris did modelling of thermal conductivity calculation of Si based nanostructured (NWs and nanogarined) materials by using Boltzmann transport equation and Monte Carlo simulation technique. Later, he worked as a postdoctoral researcher at Prof. Georg Madsen group at ICAMS, Rühr Universität Bochum on calculation of defect phase stability in binary chalcogenide and thermoelectric properties in these materials. Currently, he is working on the thermal and electron transport mechanism in alloy materials and developing a simple predictive model for thermal and electron transport in 2D and nanostructure materials for efficient design of thermoelectric device. His group also interested for electron and spin transport properties in hetrostructure interface and working on the electronic and spintronic properties of the interface from the atomistic calculation based on density functional theory.
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.
