Description
Tin Selenide Product Overview
Tin(II) selenide (SnSe) is a dark gray, metallic-looking solid with a layered orthorhombic crystal structure. It is a p-type semiconductor with a band gap of roughly 0.9 eV and very low thermal conductivity, which makes it attractive for converting heat into electricity.
SnSe became widely known after single crystals were reported in 2014 to reach a thermoelectric figure of merit (ZT) of about 2.6 at 923 K along one crystal axis. Polycrystalline and doped materials typically show lower values, and current research focuses on bringing their performance closer to single crystals. It is often compared with established thermoelectrics such as Bismuth telluride.
Beyond thermoelectrics, tin selenide is investigated for photovoltaic absorbers, photodetectors, phase-change memory and as an anode material for sodium- and lithium-ion batteries. Related chalcogenides include Tin Diselenide and Zinc selenide.

Frequently Asked Questions
Will SnSe powder reach a ZT of 2.6?
No. The value of about 2.6 was measured on single crystals along one direction. Polycrystalline powders show lower values that depend on processing and doping.
Which purities and forms are available?
Purities from 99.9% to 99.999% can be offered, as powder or crystals. Please specify your form and particle size when requesting a quote.
How can I get a price and documents?
Prices depend on quantity, packaging and destination. Contact us with your required volume to receive a quotation together with the CoA and SDS.
