Germanium Telluride GeTe, is black crystal, CAS 12025-39-7, MW 200.24, density 6.14g/cm³, melting point 725°C, and insoluble in water. Germanium Telluride crystal is an ionic crystal and compound semiconductor, which has a direct band gap of 0.23eV wide at room temperature, and belongs to narrow energy gap semiconductor. It is stable under normal temperature and pressure, and shows semimetallic conduction and ferroelectric. There are three major crystalline forms of this product, room-temperature α (rhombohedral) and γ (orthorhombic) structures and high-temperature β (cubic, rocksalt-type) phase, α phase being most common one. Germanium Telluride, a novel 2D material, has attracted much attention due to its excellent electronic and optical properties. The preparation of Germanium Telluride is by heating Germanium and Tellurium to their melting point in a vacuum quartz tube and recrystallizing to obtain GeTe, but single crystal GeTe can be obtained by zone floating method. It is used as a material for infrared light emission and detection. Meanwhile, Germanium telluride is a well-known phase change material PCM used in non-volatile memory cells and radio frequency switches. Germanium Telluride at Western Minmetals (SC) Corporation can be delivered with 99.99% 4N, 99.999% 5N purity in form of powder, lump, chunk, bulk crystal chunk and rod etc or as customized specification.
