Chemical treatment of monocrystalline cadmium telluride and Cd₁₋xMnxTe solid solutions by Н₂О₂–НІ–citric acid etchant compositions

摘要

Dissolution of CdTe and Cd₁₋xMnxTe single crystals in aqueous solutions ofudН₂О₂–НІ–citric acid system has been studied. The surfaces of equal etching rates wereudconstructed and the limiting stages of the dissolution process were ascertained. Alsouddetermined were the concentration limits for the solutions that can be used for chemicaludpolishing the above-mentioned semiconductor materials.
