Indium Sulfide

Indium sulfide sputtering target is a material used in magnetron sputtering and other coating techniques. Thin films of indium sulphide, of which indium sulfide is the main component, can be deposited on a substrate, making it a functional material with potential applications in semiconductors and optoelectronics.

Properties

Chemical formula: In₂S₃, indicating a compound consisting of two indium atoms and three sulfur atoms.

Chemical Stability: It has a certain chemical stability at room temperature and pressure, but may react chemically under certain conditions such as high temperature and strong oxidising agents. For example, when heated in air, it turns into indium trioxide. Soluble in aqueous ammonium sulfide solution.

Appearance: Usually red in colour.

Density: approx. 5.18 x 10³kg/m³.

Melting point: about 679°C

Crystal structure: Has a specific crystal structure, which has an important influence on the arrangement of atoms and film growth during sputtering.

Sputtering rate: Specific sputtering rate under certain sputtering power and sputtering gas conditions. The sputtering rate affects the efficiency and productivity of thin film deposition.

Film Thickness Uniformity: The ability to create a uniform film thickness distribution on the substrate is important for the preparation of high quality films. High-quality indium sulfide sputtering targets can achieve high film thickness uniformity.

Adhesion: Good adhesion of the sputtered film to the substrate ensures that the film will not peel off during use.
