Zinc telluride powder is an important semiconductor material.
Basic information:
Chemical formula: ZnTe.
Molecular weight: 192.97.
CAS number: 1315-11-3.
Appearance: Usually grey or brownish-red powder. Ruby red cubic crystals can be obtained by sublimation.
Density: Relative density of about 6.34 g/cm³ (15 ° C or 25 ° C).
Melting point: The melting point is high, about 1238.5℃.
Crystal structure: It generally has a cubic (sphalerite crystal) structure, but it can also be prepared into rock salt crystals or hexagonal crystals (wurtzite structure).
Preparation method:
Vacuum melting method: In a vacuum environment, high purity zinc and tellurium are heated to more than 800 ° C to 900 ° C, so that they are melted and fully mixed, and then cooled and solidified to obtain zinc telluride material, and then ground into powder.
Application field:
Semiconductor field: It can be used to make semiconductor devices, such as field-effect transistors, light-emitting diodes, laser diodes, etc., and has application potential in high-frequency, high-speed electronic devices and optoelectronic devices.
Solar cell field: can be used as the absorption layer or buffer layer material of thin film solar cells, which helps to improve the photoelectric conversion efficiency of solar cells.
Optical field: It can be used as fluorescent materials and phosphorescent materials, and can also be used to make optical devices such as infrared detectors, which has certain application value in infrared optical systems.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo.
