CONTACT INFORMATION :

Research Interest

  • Thermal and electronic transport.
  • Nanomaterials, Nanotechnology, Computational Nanoscience.
  • Thermoelectrics, Renewable energy.

Research Highlights

  • Theoretical model for predicting thermoelectric properties of TIN chalcogenides
  • 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.
