Tungsten Telluride

Tungsten telluride target is an important sputtering target.

Basic information:

Composition: Composed of two elements, tungsten (W) and tellurium (Te), chemical formula WTe₂.

Appearance: Usually gray or black blocky solid, the specific color and appearance may vary depending on the preparation method and purity.

Purity: Common purity levels are 99.9%, 99.99%, etc. High purity tungsten telluride targets are very important to ensure the quality and performance of sputtered films.

Hardness: It has a certain hardness and can withstand the ion bombardment during sputtering.

Electrical conductivity: It has good electrical conductivity, which is very important for charge transfer and uniformity of the film during sputtering.

Preparation method:

Powder metallurgy method: tungsten powder and tellurium powder are mixed according to a certain proportion, and then the target material is prepared by pressing, sintering and other processes.

Vacuum melting method: Heating tungsten and tellurium to high temperatures in a vacuum environment to melt them, and then cooling and solidifying into targets.

Physical vapor deposition: the thin film of tungsten telluride is prepared first, and then the thin film is stripped off the substrate to make the target material.

Application field:

Semiconductor field: can be used to prepare semiconductor devices, such as transistors, integrated circuits, etc.

Optical field: Used to prepare optical films, such as anti-reflection film, reflection film, etc.

New energy field: It is also used in new energy fields such as solar cells and fuel cells. For example, in solar cells, tungsten telluride can be used as an electrode material or a thin film material to improve the conversion efficiency of solar cells.

Research has found that tungsten telluride has superconducting properties at low temperatures, so it has also received attention in the field of superconductivity. Tungsten telluride targets can be used to prepare superconducting thin films or superconducting devices, providing material support for the development of superconducting technology.

With the rapid development of semiconductor, optics, new energy and other fields, the demand for high-performance materials is increasing. As a material with unique properties, tungsten telluride targets have broad market prospects. At the same time, with the continuous progress of preparation technology, the quality and performance of tungsten telluride targets will continue to improve, and the cost will gradually reduce, further promoting its application in various fields.
