The chemical dissolution of InAs, InSb, GaAs and GaSb crystals in (NH₄)₂Cr₂O₇-HBr-C₆H₈O₇ etching solutions has been investigated. The dissolution rate of the semiconductor materials has been measured as a function of etchant composition, stirring rate and temperature. The limiting stages of dissolut...
