'''Gallium(III) selenide''' ([[Gallium|Ga₂]][[Selenium|Se₃]]) is a [[chemical compound]]. It has a defect [[sphalerite]] (cubic form of ZnS) structure.<ref>{{Greenwood&Earnshaw}}</ref> It is a p-type semiconductor <ref>Temperature dependence of electrical conductivity and Hall effect of Ga₂Se₃ single crystal, A. E. Belal, Dr. H. A. El-shaikh, I. A. Ashraf Crystal Research and Technology,30, 1 , 135 - 139</ref>

It can be formed by union of the elements. It hydrolyses slowly in water and quickly in mineral acids to form toxic [[hydrogen selenide]] gas. The reducing capabilities of the selenide ion make it vulnerable to oxidizing agents. Keep it away from bases.
