Title: Engineering the thermoelectric response of transition-metal dichalcogenides

Speaker: Dr. S. Kumar, Physical Sciences and Engineering Division, King Abdullah University of Science and Technology, KSA.

Abstract: Current demand to sustain our energy needs calls for the clean energy resources compared to fossil fuels. Scavenging of waste heat from industrial processes, exhaust engines etc. using thermoelectric materials has attracted a lot of attention during the last decade. Efficiency of thermoelectrics to convert heat into electrical energy is characterized by the figure of merit, which depends upon its Seebeck coefficient, electrical conductivity, electronic and lattice thermal conductivity. In the talk, I will discuss how to optimize at atomic level the figure of merit, hence provide a new direction to search for the best thermoelectrics, especially transition-metal dichalcogenides.
