Cleaning method of InSb [111] B of n-InSb [111] A/B for the growth of epitaxial layers by liquid phase epitaxy

The crystal structure of InSb111]A/B surfaces shows that this structure is polarized.This means that the surfaces of InSb111]A and InSb111]B contain two different crystallized directions and they have different physical and chemical properties.Experiments were carried out on the InSb111]A/B surfaces,showing that tartaric acid etchant could create a very smooth surface on the InSb111]B without any traces of oxides and etch pit but simultaneously create etch pit on InSb111]A surfaces.After lapping and p...
