Zinc telluride particles are an important semiconductor material.
Basic information:
Chemical formula: ZnTe, composed of zinc (Zn) and tellurium (Te).
Molecular weight: 193.988.
CAS: 1315-11-3.
Appearance: Usually gray or brownish-red powder solid, through sublimation to obtain ruby red cubic crystals.
Density: The relative density is about 6.34 g/cm³ (25 ° C).
Crystal structure: It has two crystal structures: cubic crystal type and hexagonal crystal type.
Melting point: The melting point is higher, 1238.5℃.
Preparation method:
Vacuum melting method: In a vacuum environment, high purity zinc and tellurium are heated to a certain temperature (usually above 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 particles.
Powder metallurgy method: the zinc powder and tellurium powder mixed according to a certain proportion, after grinding, drying and other treatment, sintered under high temperature and high pressure, to obtain zinc telluride block material, and finally crushed into particles.
Application field:
Semiconductor field: As an important semiconductor material, it can be used to prepare semiconductor devices, such as field-effect transistors, light-emitting diodes, laser diodes, etc., which has potential application value in high-frequency and high-speed electronic devices and optoelectronic devices.
Solar cell field: It can be applied to the absorption layer or buffer layer of thin film solar cells, etc. to help improve the photoelectric conversion efficiency of solar cells.
Optical field: It has certain applications in optics, which can be used to make optical coatings, optical filters and other optical devices, and can also be used as optical rectification THz radiation source and detection material.
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.
