A systematic study of unrelaxed and relaxed surface characters on the TiO2 (101) surface has been carried out by first-principles calculations using plane-wave pseudopotential method. We find that O2c atoms have an inward relaxation of 0.012 Å and Ti5c atoms have an outward relaxation of 0.155...

The growth mode and electronic structure of the vapor-deposited Ag overlayer on the ${\rm ZnO}(10\overline{1}0)$ surface is investigated by angle-resolved photoemission spectroscopy utilizing synchrotron radiation. The coverage dependent measurements of the two-dimensional band structure by the...

Carrier density of a two-dimensional electron gas (2DEG) in Al0.3Ga0.7N/GaN and Al0.3Ga0.7N/AlN/GaN heterostructures was investigated by performing Shubnikov-de Haas (SdH) measurements. The angular-dependent SdH measurements and the fast Fourier transformation results for the SdH data indicated...

Oxygen adsorption on the surface of polycrystalline palladium has been studied by the photoelectron spectroscopy method in a wide range of oxygen exposure and temperatures, starting with the earliest stages of adsorption to the formation of the surface compound of PdO-type. Based on the analysis...
