The authors have examined the damaged layers on cadmium selenide single crystals after chemical polishing in alcoholic bromine solutions. The crystals were grown by directional crystallization and were cut on (0001) planes or had (01/anti/10) cleavage surfaces. Dynamic chemical polishing was used with 3 vol % bromine in ethanol with a constant stirring rate at room temperature. The surface composition was determined by x-ray photoelectron spectroscopy. Ellipsometry was used to estimate the oxide film thicknesses after various treatments. They examined the surface resistance as affected by the treatment, where electrodes made of eutectic indium-gallium alloy were used with a probe method. The dark surface resistance is dependent on the treatment. Chemical polishing with alcoholic bromine produced a damaged layer in cadmium selenide which differs from that after mechanical treatment.
