“…Furthermore, the recorded line profile along the A-AЈ ͓͑-1-11͔ direction of the ͑111͒ plane͒ shown in Fig. 24 On the other hand, the ͑111͒1 ϫ 1 structure and the regular width of the ͑111͒ plane seems to lead to the LEED pattern, which is composed of the strong spots with hexagonal symmetry and the weak "n / 5" fractional spots. On the other hand, the width of the narrow ͑111͒ plane is ϳ1.8 nm.…”

B 17, 983 (1999); 10.1116/1.590680Nanometer scale selective etching of Si(111) surface using silicon nitride islandsWe have investigated the Sb-induced reconstruction of the Si͑112͒ surface using low energy electron diffraction ͑LEED͒ and scanning tunneling microscopy ͑STM͒. Upon Sb adsorption on the clean reconstructed Si͑112͒ surface at 300°C, the Si͑112͒-͑111͒1 ϫ 1-Sb surface was obtained. The present STM study gathered the following findings: The Sb-adsorbed Si͑112͒ surface is composed of saw toothlike nanofacets, which are composed of the ͑557͒ plane and the ͑111͒ plane. The ͑557͒ plane consists of about five ͑111͒ planes with five times the width of bulk-terminated ͑111͒1 ϫ 1 unit cell and ͑001͒ plane. It is also about 8.5 Å in height and tilted at a 9.9°angle with respect to the basal plane ͑112͒. Based on observation, it appears that the Sb atoms on the ͑111͒ planes substitute for the topmost Si atoms on the ideal Si͑111͒1 ϫ 1 surface. Based on the STM results, we suggest a structural model and discuss the reconstructing mechanism of nanofacets induced by Sb adsorption.
