Fermi level positions, ionisation potentials, and work functions of acceptor-, donor-, and undoped CeO2 have been determined by means of in situ photoelectron spectroscopy on films grown with different surface orientation and preparation conditions.

The exchange of 18O between gaseous molecular oxygen and thin-film samples of Ce0.99Gd0.01O1.995 with two different, nominal surface orientations [(111) and (110)] was studied. Oxygen isotope exchange experiments were conducted in the temperature ran

We studied the behavior of oxygen interstitials in donor-doped ceria using equilibrium conductivity measurements, conductivity relaxation experiments, and (18O2/16O2) isotope exchange experiments. ...

The influence of dopant species and concentration on the grain boundary scattering of differently doped In 2 O 3 thin films is studied by means of room temperature and temperature dependent Hall effect measurements. Barrier heights at grain boundarie

Differently oriented CeO2 thin films were prepared by radio frequency magnetron sputter deposition from a nominally undoped CeO2 target. (111), (110) and (100) oriented films were achieved by deposition onto Al2O3(0001)/Pt(111), MgO(110)/Pt(110) and

CuO thin films were grown by reactive magnetron sputtering and analyzed with respect to their structural, chemical, optical, and electrical properties. The films are strongly p-type with carrier concentrations of ∼ 1020 cm−3. Carrier accumulation

Electroless plating is a facile wet-chemical process for the creation of metal thin films on arbitrary substrates, which can be used to produce intricate nanomaterials. In this study, we demonstrate how nanotubes and nanowires can be electrolessly de

Hydrogen doped In2O3 thin films were prepared by room temperature sputter deposition with the addition of H2O to the sputter gas. By subsequent vacuum annealing, the films obtain high mobility up to 90 cm2/Vs. The films were analyzed in situ by X-ray
