Profile imaging of the InSb{111}A,B-(2x2) surfaces

摘要

The InSb{111}A,B-(2 x 2) surfaces have been investigated using ultrahigh vacuum high-resolution transmission electron microscopy in the profile-imaging geometry. The multi-slice image simulation for these two surfaces shows that a through-focal series of experimental images strongly supports the In-vacancy buckling model for the InSb(111)A-(2 x 2) surface and the T-4-site Sb trimer model for the InSb(111)B-(2 x 2)surface.
