Sb-induced reconstruction of the Si(112) surface
LEED patterns taken from the surface . The bright spots originated from the structure and the weak spots are “” fractional.
(a) Large-scale STM image of the surface taken at a tip bias of . (b) image of the nanofacets, (c) the atomic resolution image of the narrow (111) plane, (d) line profile from X to in 2(a), and (e) line profile from P to in (b).
(a) Schematic model of reconstruction of the surface. (b) Schematic depicting relative direction of nanofacets to basal plane (112) surface. (c) Sb adsorption sites on the (111) plane in the surface. Open circles and filled (shaded) circles represent Si and Sb atoms, respectively.
Table for relationship between the corresponding angle and unit cell length L in silicon.
