VD0869 Tin Telluride (SnTe) Evaporation Materials

Tin Telluride (SnTe) Evaporation Materials Description

Tin Telluride (SnTe) is a semiconductor material composed of tin and tellurium and is known for its strong thermoelectric properties. As an evaporation material, SnTe is commonly used to deposit thin films for applications like thermoelectric generators, infrared detectors, and solar cells. It has a high thermoelectric efficiency, particularly when doped, making it ideal for energy conversion and cooling. SnTe has a direct bandgap of around 0.18 eV, which makes it effective in infrared sensing. The material is stable and available in high purity, ensuring the deposition of high-quality, stable films. SnTe also has moderate electrical conductivity and low thermal conductivity, enhancing its thermoelectric performance. It can be easily deposited using methods like thermal evaporation and molecular beam epitaxy (MBE), resulting in smooth films with controlled properties. SnTe is generally safe to handle under standard conditions, making it suitable for a wide range of electronic and optoelectronic applications.
