Abstract

Scanning tunneling microscopy (STM) has been used to study the surface structure and the electrtonic states of α-Sn(111) films grown heteroepitaxially on InSb(111)A-2 × 2). The wide ares STM image shown a large number of domains existing on the terrce, each having an average size of about 100 Å and a period of (2 × 2). The magnifide image shows evidence of a T4-adatom and rest-atom pair reconstructed structure for the α-Sn(111)-(2 × 2) surface, as expected from the ab initio calculations. Furthermore, the result that the adatom and the rest-atom appear simultaneously in the occupied state image can be explained by the existence of back bond states in the adatom configuration.
