Predicting Thin Film Stoichiometry In V-O2 Reactive Sputtering

Medžiagotyra, 2015
The electrical, optical and mechanical properties of compound oxides film depend strongly on the composition of the film, especially for vanadium oxide thin films, since the vanadium-oxygen phase diagram includes mixed valence oxides with two or more ...

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

Advanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Structure and transparent conductive properties of F-doped ZnO(FZO) thin films prepared by reactive magnetron sputtering

Cailiao gongcheng, 2021
F-doped ZnO (FZO) films were prepared by reactive sputtering using Zn/ZnO/ZnF2 mixture as the target at substrate temperature (Ts) of 150℃ and 300℃ and sputtering atmosphere of Ar+O2 and Ar+H2. The effect of gas flux, Ts, and sputtering atmosphere on the

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
