We have examined, using angular scanned photoelectron diffraction (PED), the effect of the saturation of dangling bonds of Si(1 1 1) surfaces with atomic As on the Ag thin films growth. The intensity variation of the Ag 3d core-level was monitorised

In the present work HCl–propanol treated and vacuum annealed GaAs(1 0 0) surfaces were studied by means of soft X-ray photoemission and reflectance anisotropy spectroscopies (SXPS, RAS). On the as-treated surface, As 3d and Ga 3d core level spectra

The As-terminated Si surface has an ideally flat monolayer of As atoms at the outermost layer, showing a nonreconstructed (1×1) symmetry with one extra valence electron on each As atom, and setting a passivation, on the silicon surface, remarkable f

We demonstrate a new approach to study semiconductor surface passivation. This approach, which we have applied to the case of GaAs(100) passivation by sodium sulfide water solutions, consists of using both reflectance anisotropy spectroscopy during p

The room temperature deposition of small amounts of Cs on the InAs(110) surface induces the highest Fermi-level pinning position (~ 0.6 eV) above the conduction band minimum ever met for any semiconductor. The Fermi-level movement is monitored by cor

The effect of alkali-metal overlayers (K, Cs) on the room-temperature oxidation of the Ge (100)2 × 1 surface in the presence of molecular oxygen was investigated by core-level and valence-band photoemission spectroscopy using synchrotron radiation.

The valence and core level spectra of chemically prepared, ideally H-terminated Si(111) surfaces are characterized by remarkably sharp features. The valence band levels and their dispersion are well described by first-principles calculations using a

Angle-resolved photoemission spectroscopy has been used to study the valence band structure of the Zn0.15Hg0.85Te alloy. Data were collected for emission along the normal to the cleaved (110) face of these crystals as a function of UV photon energy i

We have studied the development of Schottky barrier heights during the initial formation of Bi/Si(100) and Bi(111) interfaces. In the submonolayer regime we have followed the band bending changes using synchrotron radiation core-level spectroscopy. I

Unreactive metal-semiconductor systems are scarce but may serve as prototypes to understand the initial stages of the formation of Schottky barriers; they may provide a good medium in which to study coverage dependent structural arrangements, bonding
