Abstract
IT is commonly supposed by solid-state physicists that quaternary and quinary tetrahedral compounds (such as are listed in a recent article by Pamplin1) will prove exceedingly difficult to prepare. We have recently prepared alloys with compositions in the system Znx Cd1−x Sn As2. (ref. 2) and found complete chalcopyrite solid solution. Single-phase powders were obtained after an anneal for several weeks at 600° C. Such annealing treatment is fairly typical for alloys in which the anion (here arsenic) lattice is populated with a single type of atom. When the anion is varied as InAs–InSb or GaAs–GsSb much longer anneal times are required3.
