Imaging the surface Fermi contour on Cu(110) with scanning tunneling microscopy

The Cu(110) surface has two projected bulk band gaps at the edges of the surface Brillouin zone. One of the surface states in these gaps crosses the Fermi level. The corresponding two-dimensional Fermi contour has been imaged using the Fourier transform STM method. By studying the Fourier component intensity distribution, information about the Bloch wave function is extracted. (C) 2000 Elsevier Science B.V. All rights reserved.
