Abstract

We have investigated the structure of double steps on Si(113) surfaces miscut along a low symmetry azimuth, using scanning tunneling microscopy (STM). To estimate the kink excitation energies, distributions of kink lengths and kink-kink separation distances have been measured from the STM images with atomic resolution. We compare the results with predictions calculated using terrace-step-kink models. The results show that the energy cost of the kink of double unit length is more than two times that of one unit length. We discuss the relevance of this result to the observed step shapes.
