Bismuth selenide (Bi2Se3) is a gray powder that is a compound of bismuth and selenium also known as bismuth(III) selenide. It is a semiconductor and a thermoelectric material. While perfect stoichiometric bismuth selenide should be a semiconductor (with a gap of 0.3 eV) naturally occurring selenium vacancies act as electron donors and it often acts as a semimetal.

Material Notes

Bismuth Selenide Sputtering Target, Purity is 99.99%; Circular: Diameter <= 14inch, Thickness >= 1mm; Block: Length <= 32inch, Width <= 12inch, Thickness >= 1mm. Hazardous shipping charges may apply. Indium bonding is recommended for this material, due to some of its characteristics not amenable to sputtering like brittleness, low thermal conductivity. This material has a low thermal conductivity are susceptible to thermal shock.
