General

Germanium telluride (GeTe) is a chemical compound of germanium and tellurium and is a component of chalcogenide glasses. It shows semimetallic conduction and ferroelectric behaviour.Germanium telluride exists in three major crystalline forms, room-temperature rhombohedral and orthorhombic structures and high-temperature (cubic, rocksalt-type) phase; Rhombohedral phase being most phase for pure GeTe below the ferroelectric Curie temperature of approximately 670 K.Doped germanium telluride is a low temperature superconductor.

Material Notes

Germanium Telluride Sputtering Target, Purity is 99.999%; Circular: Diameter <= 14inch, Thickness >= 1mm; Block: Length <= 32inch, Width <= 12inch, Thickness >= 1mm.
