Abstract

Reflection anisotropy spectroscopy (RAS) studies are reported of Si(111)-5x2-Au structures grown on substrates with different offcuts and step densities. Such substrates produce a predominant domain on the (111) terrace that would otherwise produce a negligible RAS signal, due to domain averaging. Changes in the RAS spectra with offcut angle are observed in the 1 to 3 eV region, where Au-induced structures appear. Results from offcuts towards [(11) over bar2] of 2 degrees, 3 degrees, 9.5 degrees, and -4 degrees are presented. The variation in the RAS spectra is consistent with different populations of single- and double-chain gold structures formed in the region of the steps.
