Nanostructured CuWO4/WO3-x films prepared by reactive magnetron sputtering for hydrogen sensing

High-purity films consisting of copper tungstate (CuWO4) and sub-stoichiometric tungsten oxide (WO3-x) were prepared by reactive sputter deposition. An original two-step deposition process was applied for their synthesis. First, a tungsten oxide thin film was deposited by dc magnetron sputtering ...

High‑performance thermochromic VO2‑based coatings with a low transition temperature deposited on glass by a scalable technique

We report on high-performance thermochromic ZrO2/V0.982W0.018O2/ZrO2 coatings with a low transition temperature prepared on glass by a low-temperature scalable deposition technique. The V0.982W0.018O2 layers were deposited by a controlled high-power impulse magnetron sputtering of V target, combined w...

Magnetronové naprašování vrstev s vylepšenými mechanickými a tribologickými vlastnostmi

High hardness, toughness and low coefficient of friction are the basic requirements for wear-resistant materials. This thesis deals with the preparation and characterization of the films based on Al-Si and Ti-W (beta-Ti) alloys, W metal, Al-Si-N and W-N ceramics with improved mechanical ...

PRVKOVÉ SLOŽENÍ A STRUKTURA TENKOVRSTVÝCH MATERIÁLŮ A JEJICH KORELACE S MATERIÁLOVÝMI VLASTNOSTMI

This thesis is focused on the analysis of elemental composition (by X-ray fluorescence method) and the structure (by X-ray diffraction method) of four types of the new thin-film materials prepared by different methods of magnetron deposition. These are the following materials: A. ...

Extraordinary high-temperature behavior of electrically conductive Hf7B23Si22C6N40 ceramic film

The high-temperature behavior of an electrically conductive, opaque and hard Hf7B23Si22C6N40 ceramic film with an amorphous structure was systematically investigated in air up to 1700 °C and inert gases up to 1600 °C. The film was prepared by reactive pulsed dc magnetron sputter de...
