we have used a combination of scanning tunneling microscopy (stm) and low energy electron diffraction to investigate the au-induced morphology of vicinal si samples miscut from (111) by 3.8°, and 12.3° toward [112]. the surface morphology changes dramatically with au coverage on both samples. on the 3.8° samples, gold deposition leads to the formation of the (775) facets. the (775) facet is orientated 8.5° toward [112] and characterized by 1-d chains running along [110] with a spacing of 21.3 a. the formation of the (775) facet is consistent with previous ideas that it represents a low energy facet on these surfaces. on the 12.3° sample no single low energy facet was observed in the coverage range (0-0.24ml) investigated. instead, (13 13 7), (995), and (553) facets are formed at 0.10 ml, 0.20 ml, and 0.24 ml respectively.
