Angle resolved photoemission spectra from the Si(001) surface have been calculated within the highly accurate one-step model. These spin integrated constant final state spectra for the valence bands have been investigated as a function of the emission direction of electrons. Especially, differences bet...

The surface electronic properties of the thin films have been studied by angle integrated photoemission spectroscopy, using synchrotron radiation with photon energy ranging from 50 to 200 eV. Spectra have been measured of the W 4f core levels and of the valence band (VB). The W 4f line shape...
X-ray photoelectron (XPS) and electron-energy-loss spectroscopies have been employed to investigate the valence- and conduction-band densities of states of the sapphire (1102) surface. The photoemission spectrum of the valence-band region has been adjusted to remove cross-section effects and compared...

Surface electrons are directly excited by optical transitions from the conduction band (CB) to the second surface state (SS). Bulk electrons are directly excited by optical transitions from the valence band (VB) to the CB. In this work, we employ the terahertz (THz) emission spectroscopy ...
