ST6595 Tin Selenide Target (SnSe)

Tin Selenide Target (SnSe) Description

The Tin Selenide Target (SnSe-Target) exhibits a unique combination of structural, electrical, and thermal properties, making it highly valuable for thin-film deposition. It crystallises in an orthorhombic layered structure, which allows for anisotropic charge transport and excellent thermoelectric behaviour. The target typically has a high purity (≥99.9%), ensuring minimal contamination during sputtering. SnSe possesses a relatively low melting point (~861°C) and a moderate density (~6.18 g/cm³), facilitating uniform film deposition. Its semiconducting nature, characterised by a narrow and tunable bandgap (~0.9-1.3 eV depending on the crystallographic direction), allows for precise control over the electronic and optical properties of the resulting thin films. Furthermore, SnSe demonstrates low thermal conductivity and a high Seebeck coefficient, rendering it an ideal material for energy harvesting applications. The mechanical stability of the target and its chemical compatibility with various substrates support its use in high-efficiency thermoelectric, optoelectronic, and photovoltaic devices.

1. Raw Materials - Tin (Sn)

Tin is a soft, malleable, silver-white metal with atomic number 50 and belongs to group 14 in the periodic table. It has a relatively low melting point of approximately 231.9 °C and a density of 7.31 g/cm³. Tin is known for its excellent corrosion resistance and forms a protective oxide layer that prevents further oxidation, hence it is used to coat other metals to prevent rusting (e.g., tin-coated steel). It is also a crucial component of several alloys, such as bronze (with copper) and solder (with lead or silver). Tin exhibits good electrical conductivity and is chemically stable, making it favourable for use in electronics, coatings, and modern materials.
