Description

Product Overview

The Tin Selenide (SnSe) Target stands out due to its unique blend of structural integrity, electrical efficiency, and thermal characteristics, making it indispensable in thin film deposition processes. SnSe crystallizes in an orthorhombic layered structure, which facilitates anisotropic charge transport and exemplary thermoelectric performance. Manufactured with a high purity level of ≥99.9%, the SnSe target minimizes contamination during sputtering, ensuring high-quality thin films. With a melting point of approximately 861 °C and a density around 6.18 g/cm³, SnSe allows for uniform film deposition. Its semiconducting nature, featuring a narrow and adjustable bandgap (~0.9-1.3 eV depending on crystallographic orientation), provides precise control over the electronic and optical properties of the deposited films. Additionally, SnSe boasts low thermal conductivity and a high Seebeck coefficient, making it ideal for efficient energy harvesting applications. The target’s mechanical robustness and chemical compatibility with a variety of substrates further enhance its suitability for high-efficiency thermoelectric, optoelectronic, and photovoltaic devices.
