Abstract
The (3 X 3) reconstruction of the InSb((111) over bar) surface has bee n investigated by grazing incidence X-ray diffraction and scanning tun neling microscopy. The structure is characterized by 6-atom rings on t op of a slightly buckled InSb top double layer. Two types of rings hav e 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 a re consistent with the concept of rehybridization and depolarization w hich explains the reconstructions of the (111) and (110) surfaces.
