Abstract
A strong, gold-induced surface state is found on single-domain Si(111)-(5 X 2)-Au at low temperatures. Its band dispersion is one dimensional near the Fermi level Er and gradually becomes two dimensional towards the bottom of the band, thus providing a model for a continuous transition in dimensiona lity. A Peierls-like gap is observed in the one-dimensional portion of the band near EF.
