✦ Synopsis
A useful method is presented to control the stoichiometric composition y in Cd 1+y (S x Se 1Àx ) and Zn 1+y (S x Se 1Àx ) systems. The stoichiometry y is controlled through vapor growth process by regulating the sum of chalcogen partial pressures P ps ð¼P S 2 þ P Se 2 Þ; and by keeping the pressure ratio P r ð¼P S 2 =P Se 2 Þ constant in each growth experiment. The electrical properties of the grown crystal change obviously depending on P ps and it is confirmed that the deviation y from stoichiometric composition y is effectively controlled without changing the composition x. The applicability of this method to other II-VI solid solutions is presented.
