Metal Oxide Semiconductor Material for Thermoelectric Generators
- Summary
- Purdue University researchers have developed a new metal oxide semiconductor material for use in thermoelectric generators. This new material can operate at higher temperatures and for longer periods than conventional materials. It also exhibits low thermal conductivity for a metal oxide based semiconductor, meaning it can reach higher ZT values than previous oxide materials.

- *Background
- A thermoelectric device converts a temperature difference into an electric potential (voltage), generating electrical power from heat. These devices are rated based on a thermoelectric figure of merit (ZT). Current thermoelectric materials are limited by their low melting or decomposition temperature. There is a need for a material that can produce a high ZT value in high temperature applications.
