Step dynamics in faceting on vicinal Si(113) surfaces

Koichi Sudoh, Hiroshi Iwasaki

Abstract

Faceting is a thermodynamic phase separation where a surface with some arbitrary macroscopic orientation breaks up into a hill and valley structure. Vicinal Si(113) surfaces are typical systems where faceting occurs due to short-range attractive step–step interactions. This paper reviews our recent studies on step dynamics involved in faceting on vicinal Si(113) surfaces, by high temperature scanning tunnelling microscopy and analysis based on the continuum step model.
