چکیده

The wetting of thin Ag films on Cu 111 is characterized in detail with angle-resolved photoelectron spectroscopy. After constructing disordered Ag films on Cu 111 , we monitored the evolution of their layer-resolved Shockley states during wetting. Our results provide the first observation of a transitional state, which implies a coexistence of clean Cu 111 , 1 ML of Ag on Cu 111 , and 2 ML of Ag on Cu 111 . The evolution of these Shockley states indicates a two-process model of wetting.

Evidence for the half-metallic ferromagnetic state of Fe3O4 by spin-resolved photoelectron

The spin-dependent electronic structure of thin epitaxial films of magnetite, Fe3O4(111), has been investigated at room temperature by means of spin-, energy-, and angle-resolved photoemission spectroscopy. Near the Fermi energy EF a spin polarization of 2(8065)% is found. The spin-resolved photoemission spectra for binding energies between 1.5 eV and EF show good agreement with spin-split band...

Transition from disorder to order in thin metallic films studied with angle-resolved photoelectron spectroscopy.

The transition from disorder to order in Ag film grown on Au(111) was investigated by monitoring the quantum well states using angle-resolved photoelectron spectroscopy. Our results show that the binding energies do not alter, but the in-plane dispersion alters from flat to parabolic when the film is annealed. We suggest that there are isolated and ordered patches scattered across the film at a...

First principle calculations of core-level binding energy and Auger kinetic energy shifts in metallic solids

We present a brief overview of recent theoretical studies of the core-level binding energy shift (CLS) in solid metallic materials. The focus is on first principles calculations using the complete screening picture, which incorporates the initial (ground state) and final (core-ionized) state contributions of the electron photoemission process in x-ray photoelectron spectroscopy (XPS), all withi...

Fabrication of MgF2-SiO2 Nanocomposite Thin Films and Investigation of Their Optical and Hydrophobic Properties

In this research, MgF2-2%SiO2/MgF2 thin films were applied on a glass substrate. At first, MgF2 thin films with the optical thickness were deposited on the glass slide substrates. Then, MgF2-2%SiO2 thin films were deposited on the glass coated with MgF2 thin films. Finally, the nanocomposite thin films were surface treated by the PFTS solution. Characterization of the thin film was done by X-Ra...

Spin texture of Bi2Se3 thin films in the quantum tunneling limit.

By means of spin- and angle-resolved photoelectron spectroscopy we studied the spin structure of thin films of the topological insulator Bi2Se3 grown on InP(111). For thicknesses below six quintuple layers the spin-polarized metallic topological surface states interact with each other via quantum tunneling and a gap opens. Our measurements show that the resulting surface states can be described...
