The preparation of indium phosphide layers by chloride-hydride reactions

The preparation of indium phosphide by reactions between separate indium chlorides and phosphine is described. It is shown that the indium monochloride-phosphine reaction is the most favourable of the three possible reactions. It is demonstrated that various growth rates are possible over a range of temperatures, that good morphological layers can be obtained along with reasonable electrical characteristics. Explanations are advanced for the chemical process and the limitations on layer properties encountered.
