Similarity of Si(110)5×1 and Si(111)2×1 surfaces

Abstract
Angle-resolved photoelectron spectroscopy has been used to study the electronic structure of Si(110) surfaces. On the 5×1 reconstructed surface a dangling-bond band with a dispersion of 0.35 eV is found. In a comparison with the dangling-bond band on Si(111)2×1 there are several similarities, which are discussed in terms of the common chainlike structures of the ideal Si(110) surface and the π-bonded chain model of Si(111)2×1.
