AbstractThe electronic states at the Fermi surface determine diverse properties such as magnetism, chemical bonding, and phonon-electron coupling. Using a conventional hemispherical analyzer at the ultraESCA beamline 7.0 of the Advanced Light Source, we have measured Fermi contours of the bulk and surface states of Cu(001) and Ag(001). For bulk states, we used uniform sampling in k-space by varying both the electron takeoff angle as well as the photon energy. Three-dimensional plots (in k-space) of bulk and surface states at the Fermi level can easily be achieved within one or two synchrotron shifts. Surface states, whose momentum is independent of k-perpendicular, are easily mapped if sufficiently dense angular sampling is performed. The states crossing the Fermi level at X in the surface Brillouin Zone of Cu(100) and Ag(100) are presented as examples.

The Individual

The traditional Hume-Rothery phases are Cu-bronzes or other (three-dimensional) alloys, which show a series of phase transitions at fixed electron-per-atom ratios, independent of the particular atomic constituents. The transitions are driven by Fermi surface nesting within the individual phases. It is shown that similar transitions appear to be a pervasive feature of two-dimensional systems. Examples are given involving graphite intercalation compounds, organic superconductors, and the new high T c oxide superconductors.
