Nanostructured Thermoelectric Materials for Energy Applications

Abstract:

Thermoelectrics are materials that may be used in a variety of applications where there is a temperature difference. These materials can be used to produce electricity, used to replace conventional coolers or refrigerators, or as calibrated thermocouples. With the advent of nanotechnology, there is a renewed interest in these materials because it is expected that the properties of the semiconductors used to make modern thermoelectrics can be tailored to improve their otherwise low efficiencies. This presentation will focus on the physics of thermoelectrics, the applications, and our current research on SiGe superlattices.

About the speaker:
Professor David Marx is an experimental solid state physicist from the department of physics, Illinois State University, Bloomington-Normal. His research program generally includes the synthesis, structural and electrical characterization, and measurement of thermal properties of bulk, thin film, and nanocrystalline materials. Professor Marx is currently focused on energy conversion devices including photovoltaics and thermoelectrics, particularly those incorporating novel nanoscale technologies
