A new type of reconstruction on the InSb(1[combining macron]1[combining macron]1[combining macron]) surface determined by grazing incidence X-ray diffraction
Surface Science 321(3): L225-L232
The (3×3) reconstruction of the InSb(1[combining macron]1[combining macron]1[combining macron]) surface has been investigated by grazing incidence X-ray diffraction and scanning tunneling microscopy. The structure is characterized by 6-atom rings on top of a slightly buckled InSb top double layer. Two types of rings have been found, an elliptic ring consisting of 4 In and 2 Sb atoms and a trigonal ring with 3 In and 3 Sb atoms. The bond angles and lengths are consistent with the concept of rehybridization and depolarization which explains the reconstructions of the (111) and (110) surfaces.
