Abstract

A number of chalcogenides and phosphides crystallize with the tetrahedral structure in which the cations and anions are in tetrahedral positions. The II-VI compounds such as ZnS, ZnSe, CdS and CdSe are known to transmit in the far infrared. However, they are soft and decompose in air at relatively low temperatures. Efforts have been made at Brown University to improve the properties of these compounds, either by alloying them with III-V semiconductors, or by substituting transition metals such as nickel for the divalent specie.
