Tin(II) Selenide (SnSe) Crystal CAS 1315-06-6

Tin(II) selenide crystal, high purity narrow band gap semiconductor

Comprised of environmentally friendly elements

Tin(II) selenide (SnSe), CAS number 1315-06-6, is a narrow band gap semiconductor comprised of environmentally friendly and earth abundant elements.

SnSe has recently proven to be an extraordinarily promising thermoelectric material with intrinsically ultra-low lattice thermal conductivity and a record figure of merit up to 2.6 at a higher temperature (813 K). This enables direct and reversible conversion between thermal and electrical energy, and provides a viable route for power generation from waste heat.

With an indirect bandgap of 1.30 eV and direct bandgap of 1.21 eV, SnSe has great potential to be utilised as an efficient material for solar energy conversion.

SnSe belongs to the class of layered semiconductors. It is made up of tightly bound layers formed by double planes each of which consists of zigzag chains of tin and selenium atoms. At room temperature, SnSe adopts orthorhombic crystal structure which can be compared to that of black phosphorus.

Viscoelastic Transfer of 2D Material Using PDMS

Viscoelastic transfer using polydimethylsiloxane (PDMS) stamps is one of the methods used for the deterministic placement of 2D materials and the fabrication of van der Waals heterostructures. It relies on the viscoelasticity of PDMS, which behaves as an elastic solid on short time scales, but as a viscous fluid on long time scales.
