N2 - We have used scanning tunneling microscopy to study Si(113) 0.2° misoriented towards [11-bar0]. Rapid quenching of this surface from 1500–1575 K to room temperature results in a uniformly stepped single-domain surface, whereas slower cooling gives rise to clustering of steps. The thermally induced step wandering and the terrace width distribution of the uniformly stepped surface are analyzed in order to determine the strength of the energetic and entropic step-step interactions. Beside the short-range attractive step-step interaction found by Song and Mochrie [Phys. Rev. Lett. 73, 995 (1994)] on Si(113) misoriented 1°–5° towards [001], we found an anomalously strong long-range repulsive step-step interaction on Si(113) 0.2° misoriented towards [11-bar0]. The coexistence of a long-range repulsive and a short-range attractive step-step interaction may explain the transition from a uniformly stepped surface at high freeze in temperature to a faceted surface at lower freeze in temperatures.
