Bismuth Selenide Sputtering Targets

Bismuth selenide (Bi2Se3) is a gray powder, a bismuth and selenium compound, also known as bismuth(III) selenide. It is a semiconductor and a thermoelectric material. At the same time, 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.

Bismuth Selenide Sputtering Targets Information

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