Application of Phosphine Tellurides to the Preparation of Group II-VI (2-16) Semiconductor Materials

Phosphine tellurides (R sub 3 P Te, where R is an organic substituent) are potential sources of tellurium in the growth of films of II- VI materials such as mercury telluride by organometallic vapor phase epitaxy. Phosphine tellurides are useful because, being labile complexes of zerovalent tellurium, they supply the growth reactions with the equivalent of atomic tellurium at very low temperatures.
