Dispersion of Evanescent Band Gap States in Fe Clusters on GaAs(110)

January 1, 1990
Author(s)
Joseph A. Stroscio, P First, Robert A. Dragoset, L Whitman, Daniel T. Pierce, Robert Celotta
… microscopy results on the band gap states observed in tunneling to nanometer size metallic Fe clusters on GaAs(110) surfaces. In the vicinity of the Fe clusters, a continuum of gap states is found in tunneling spectra from regions of the bare semiconductor. …

Material Dependence of Electron Inelastic Mean Free Paths at Low Energies

January 1, 1990
Author(s)
Shigeo Tanuma, Cedric J. Powell, David R. Penn
… inelastic mean free paths (IMFPs) for 50-2000 eV electrons in 31 materials (27 elements and 4 compounds). We present and discuss in this paper IMFP data for aluminum and gold in the 50-2000 ev Range. Substantial differences are found in … Journal of Vacuum Science and Technology A …
