Bromine methanol solutions are extensively used in HgCdTe device processing technology. The relative reaction rates of Hg, Cd, and Te and HgCdTe with bromine in methanol have been studied. The reaction rate constants, reaction order, and some conclusions about the mechanisms of the reactions of the elements with bromine are reported here. The anisotropic nature of the reaction of the semiconductor with bromine has been demonstrated. The effects of mechanical action on the relative rates of the semiconductor constituents have been studied and are also discussed.
