Abstract
Novel compound semiconductors are of the general formula, X.sub.5 YZ.sub.4, wherein X is a member selected from the group consisting of Cu, Ag and mixtures thereof, Y is a member selected from the group consisting of Al, Ga, Tl and mixtures thereof, and Z is a member selected from the group consisting of Se, S, Te and mixtures thereof. Typical of the compound semiconductors are Cu.sub.5 AlSe.sub.4 and Ag.sub.4 AlSe.sub.4. These compound semiconductors are especially useful for making blue to UV light-emitting devices which include n-type and p-type compound semiconductor layers made of the above compound semiconductors.
