Chemical etching of Cd1 − x Mn x Te solid solution single crystals with iodine solutions in methanol

Abstract

Chemical etching of Cd_{1 − x} Mn _x Te (0.04 < x < 0.5) solid solution (ss) single crystals in I₂ + CH₃OH etching mixtures was studied. Concentration and kinetic curves of etching rates were plotted. As the manganese concentration of the solid solution increases, the rates of their etching by iodine-methanol etchants increase, too. The etchant compositions and chemical-dynamic polishing protocols for Cd_{1 − x} Mn _x Te single crystals were optimized.
