Applications

Two-dimensional (2D) transition metal dichalcogenides (TMDs) have attracted increasing attention owing to their diverse properties ranging from insulator to metal and promising for wide applications. TMDs and their 2D van der Waals heterostructures have been proposed and demonstrated in various applications, such as electronics, optoelectronics, photonics and photovoltaics.

Among TMDs, SnSe₂ has a high intrinsic electron mobility at room temperature and ultralow thermal conductivity. Furthermore, SnSe₂ exhibits pressure-induced periodic lattice distortion and, moreover its atomic structure can reversibly change from amorphous to crystalline upon laser heating, being a phase change memory material. Owing to these peculiarities, SnSe₂ has high application capabilities in several fields, including superconductivity, batteries, photodetection, photocatalysis, saturable absorbers for eye-safe lasers, and thermoelectricity .

We can offer continuous SnSe₂ film on substrates, such as sapphire, Si, Si/SiO₂, quartz etc. Substrate size is also customizable. Please contact MSE Supplies if you need bulk pricing or customization.
