About Germanium Telluride GeTe Powder:
Germanium telluride(GeTe) is a compound of germanium and tellurium, which is a component of chalcogenide glass. It has semimetallic conductivity and ferroelectric properties. There are three main types of germanium telluride crystal: α(rhomboid) and γ(orthogonal) at room temperature and β(cubic, halite) at high temperature. At the ferroelectric Curie temperature of about 670 K, the main phase of pure GeTe is the α phase. Doped germanium telluride is a low-temperature superconductor.
The germanium telluride crystal is a periodic table WTH group element compound semiconductor. Ionic crystals.Trigonometric system face center structure, b. 19G1} lining.Melting point 724 C’.It is a direct bandgap semiconductor with a room temperature forbidden bandwidth of 0.23eV. It is a narrow bandgap semiconductor with a hole mobility of 7×10-3mZilv “S)} degree prepared by melting and recombination method. Used as infrared light emission and detection materials.

How is Germanium Telluride GeTe Powder Produced?
The preparation method of germanium telluride consists of the following steps:
(1) Weigh a certain amount of germanium telluride powder into the organic solvent and mix it evenly. The ratio of the mass fraction of germanium telluride powder to the volume fraction of the organic solvent is (2100):(5100). The unit of the mass fraction is Mg and the unit of volume fraction is mL.
(2) Put the evenly mixed solution in Step (1) into the cell crusher for ultrasonic treatment;
(3) The ultrasonic germanium telluride dispersion was centrifuged, and the grayish-black supernatant was taken. The two-dimensional material germanium telluride was dispersed in the supernatant.
Applications of Germanium Telluride GeTe Powder:
Germanium telluride is a thermoelectric material.
Germanium telluride is used in thermoelectric refrigeration.
Germanium telluride is also used in infrared detection equipment and semiconductors.
GeTe is already widely used in non-volatile optical data storage, such as CD, DVD and Blu-ray, and may replace dynamic and flash random access memory. In 1987, Yamada et al. studied the phase transformation properties of GeTe and Sb2Te3 used in optical storage. The shorter crystallization time, circularity and high optical contrast make these materials a better choice than Te81Ge15Sb2S2, which has a slower transition time
The high resistivity contrast between amorphous and crystalline states and the ability to repeatedly reverse transitions make it a good candidate for RF switches. The radiofrequency requires the deposition of a thin layer of GeTe film on the surface of the substrate. Seed layer structure, precursor composition, deposition temperature, pressure, gas flow rate, precursor bubbling temperature and substrate all have an influence on membrane performance.
Storage Condition of Germanium Telluride GeTe Powder :
The damp reunion will affect GeTe powder dispersion performance and using effects, therefore, germanium telluride GeTe powder should be sealed in vacuum packing and stored in the cool and dry room, the germanium telluride can not be exposure to air. In addition, the GeTe powder should be avoided under stress.
