Copper Selenide

Copper Selenide sputtering target is a kind of material used in magnetron sputtering and other coating technologies, which can make copper and selenium atoms deposit on the substrate to form a thin film by high-energy particle bombardment, and it has important applications in photovoltaic, optoelectronic and other fields.

VIMATERIAL supplies CopperSelenide sputtering targets, all of our products support customisation and all targets can be supplied with binding service. We are a professional sup plier of inorganic chemical materials and have rich experience in sputtering targets, please contact us if you have any needs.

Physical Properties

Molecular Formula: Cu₂Se

Molecular weight: 206.063 g/mol

Appearance: grey to black target

Density: Relative density about 6.749 g/cm³.

Crystal structure: belongs to cubic crystal system, the copper and selenium atoms in its crystal structure are arranged according to a certain pattern, constituting a stable cubic crystal lattice.

Applications

Semiconductor field: Used in the manufacture of semiconductor devices, deposited on the surface of wafers to form a thin film with specific electrical properties, to help the production of integrated circuits and so on.

Photovoltaics: used as a key material in thin-film solar cells to help deposit back electrodes or conductor layers to improve cell performance and efficiency.

Photovoltaic field: used in the manufacture of photodetectors and other optoelectronic devices, through the sputtering of thin films to achieve effective detection and conversion of optical signals.

Display field: in liquid crystal display, organic light-emitting diode display and other flat panel display technology, involved in the deposition of transparent conductive film and other functional film layer, improve the display quality and performance.

Glass coating field: can form a uniform coating on the glass surface, giving the glass such as conductive, heat insulation, anti-reflective and other special properties to meet the needs of different applications.

Quality Control

Each batch of products implement the strictest quality control system, we have completed product records, product traceability with strict quality assurance. We have a complete process for the handling of non-conforming products, and will not flow the non-conforming products to the next process. We provide samples for customers’ re-inspection, and we also support the third party inspection organisations designated by customers.

Packaging and Storage

Copper Selenide sputtering targets are protected in double vacuum bags and then boxed.

Copper Selenide sputtering targets should be stored in a dry, cool, well-ventilated environment, protected from light, in sealed packages or containers, preferably filled with inert gas, and kept away from strong oxidising agents, acids and other substances that may have a chemical reaction with them, to prevent them from being contaminated with moisture, oxidation and impurities.
