Abstract
We have studied Raman scattering from CdTe 〈100〉, 〈110〉, and 〈111〉 surfaces subjected to various surface treatments. Our investigation shows that 0.1% Br/methanol etch or chemomechanical polish leaves a thin residual layer of polycrystalline Te of thickness 10–40 Å (under a tensile stress of about 8 kbar) and that this Te film can be removed by a rinse in a 1 N KOH in methanol solution.Keywords
