We have investigated the 3×2 structure on a Si(113) clean surface using scanning tunneling microscopy (STM). The results are compared with the theoretical images obtained for two proposed geometrical models. One of these models can almost account for our images. A high density of surface defects is observed on Si(113) and their structures are proposed on the basis of STM images. © 1996 The American Physical Society.
