The concept of coupling a nanometer or subnanometer scale oxide phase to a metal surface
to form a metal–oxide hybrid material with novel properties is an attractive approach in the …

Metal oxides and oxide thin films are extensively used as active catalysts and catalytic
supports, as well as in many other important technical applications. Unlike TiO 2, which is a …

Surface science has had a major influence on the understanding of processes at surfaces
relevant to catalysis. Real catalysts are complex materials, and in order to approach an …

Using an ab initio total energy approach, we study the stability of free and Ag (111)-
supported MgO (111) ultrathin films. We unravel a novel microscopic mechanism of …

The ability to engineer nearly perfect ultrathin oxide layers, up to the limit of monolayer
thickness, is a key issue for nanotechnological applications. Here we face the difficult and …

Cuprous oxide (Cu2O) crystals and films of 10–65 nm thickness are investigated via electron
diffraction, scanning tunneling microscopy (STM), and photoluminescence (PL) …

Collective rotations and tilts of oxygen polyhedra play a crucial role in the physical
properties of complex oxides such as magnetism and conductivity. Such rotations can be …

We investigate Raman spectra (100 cm− 1 to 3900 cm− 1) of magnesium oxide
nanoparticles with nominal sizes of 10 nm, 20 nm, 40 nm, 50 nm, and 300 nm. The crystal …

Ultrathin Si O 2 films on Mo (112) were synthesized using different preparation procedures
and characterized with ultraviolet photoelectron spectroscopy (UPS), metastable impact …

Crystalline MgO films with a defined level of Cr dopants (MgO Cr) are prepared by either
subsequent or simultaneous deposition of Cr and Mg atoms in an oxygen ambience onto a …
