Abstract

Three types of steps are observed on the cleaved InP(110) surface, using atomicresolution ultra-high vacuum (UHV) scanning tunneling microscopy (STM). The step edges are oriented along the (110), (111), and (112) directions. Atomic models of monatomic-height (111) and (112) steps indicate that the edges of each of these unrelaxed steps should have pairs of dangling bonds. We propose that the bonds dimerize, causing the edges to relax and form periodic structures along the edge.
