Bismuth (III) Telluride, Powder, 99.9%, -270 mesh (21 mic aps) approx

Bismuth telluride is a narrow-gap layered semiconductor used extensively in thermoelectric devices for solid-state cooling and power generation.

Bismuth telluride targets are used in sputtering processes to deposit thin films for the fabrication of micro-thermoelectric generators and sensors.

Used as a source material in physical vapor deposition to create high-performance thermoelectric thin films on various substrates.
