Abstract

âº ([(NH4)2S/(NH4)2SO4] + S) treatment improved the morphology of (111)A InAs surface. âº ([(NH4)2S/(NH4)2SO4] + S) most effective at removing In2O3 and As-O. âº In2O3 removal attributed to the availability of H3O+ through a hydrolysis reaction. âº Higher solubility of As-O in S-based solution accounts for its efficient removal.
