Structural electrical and optical properties of CdSxSe1 − x films

Complete solid solutions of CdS_xSe_{1 ? x} over the range0 ? x ? 1 were grown by pyrolytic decomposition. The films had a predominant hexagonal structure with lattice constants varying linearly with composition. At an illumination level of 10 mW cm^-2, the decay time for CdSe was 1.2 ms and decreased with increased in the background illumination, the lifetime of the majority carriers being 1 ms.
