Photoemission spectromicroscopy was used to investigate the electronic structure of TiO2 anatase single crystals and polycrystalline thin films. The stoichiometry and the degree of oxidation of as-grown crystals, as-deposited films, as well as of thermally ...
We studied the newly synthesized quasi-one-dimensional compound Nb4Te17I4. Resistivity measurements confirmed its pseudo-one-dimensional character and photoemission spectroscopy clarified the nature of its valence band states. This polytelluride is a narro ...
The electronic structures of different phosphates were studied by using the DV-X alpha cluster molecular orbital method, Experimental data on crystal structures from x-ray diffraction measurements were used to set up realistic model clusters. Theoretical X ...
The densities of states for small (TiO2)x-clusters, x = 1, 3, 6, 9, and 14, were calcd. by means of the INDO method. The shape of the valence bands' d. of states (DOS) are discussed in terms of the distribution of coordination nos. A one-slab cluster with ...
We applied the internal photoemission technique to the direct observation of deep levels together with barrier heights and band discontinuities at different semiconductor heterostructure interfaces. Its performances and capabilities are superior to those o ...
Presents a synchrotron radiation photoemission study of the upper-valence-band states of four ZrSe3-structure compounds: ZrS3, ZrSe3, ZrTe3 and HfSe3. The sulphide and selenide spectra exhibit a charac ...
Studies have been carried out on aqueous colloidal suspensions of semiconductors, principally by using laser flash-photolysis techniques, in order to scrutinize in detail the dynamics of light-induced charge transfer reactions occuring at the solid-electro ...
