摘要
Atomic-force microscopy (AFM) at ambient conditions has been applied to study the monatomic step distribution on the silicon (001) surface during sublimation at electric current heating. The computer treatment of topological and phase-contrast AFM-images was used for quantitative characterization of dynamic surface phenomena. The dependence of average terrace width on step number in the bunch was measured. Repulsion force between closer packed monatomic steps was shown whereas attractive force between the step and island separated by longer distance was revealed.
