Enhanced hydrogen response of copper-doped TiO synthesised by helium-assisted magnetron sputtering
Akash Kumar, Nirmal Kumar, David Kolenatý +4
Cu-doped TiO thin films for hydrogen sensing were synthesised by reactive DC magnetron sputtering in Ar/O/He mixtures, with the He fraction used as a control parameter for…
Boron-assisted stabilization of low-resistivity mixed-valence Cu-O thin films prepared by reactive magnetron sputtering
Nirmal Kumar, Jemal Yimer Damte, Michal Procházka +5
This study systematically investigated the influence of boron incorporation in Cu-O thin films and the effect of oxygen partial pressure () on the phase evolution, chem…
Crystalline b-Ga2O3 thin films deposited via reactive magnetron sputtering of a liquid Ga target
Petr Novak, Jan Koloros, Stanislav Haviar +2
Ga2O3 thin films were deposited by reactive magnetron sputtering from a liquid gallium target. The influence of deposition temperature, substrate type, and discharge parameters on…
Corrosion-resistant and conductive Ti-Nb-O coatings tailored for ultra-low Pt-loaded BPPs and PTLs in PEM electrolyzers
David Kolenatý, JiÅà Äapek, Stanislav Haviar +6
We develop highly corrosion-resistant and conductive Ti-Nb-O coatings for metallic components -- bipolar plates (BPPs) and porous transport layers (PTLs) -- in PEM water electrolyz…
High-performance thermochromic multilayer coatings with W-doped VO2 nanoparticles dispersed in SiO2 matrix prepared on glass at a low temperature
Jaroslav Vlcek, Michal Kaufman, Elnaz M. Nia +5
We report a high-performance thermochromic VO2-based coating prepared by using a three-step process, consisting of magnetron sputter depositions of SiO2 films and V-W films and the…
Ultra-low-resistivity nitrogen-doped p-type Cu2O thin films fabricated by reactive HiPIMS
JiÅà Rezek, Jan Koloros, JiÅà HouÅ¡ka +5
We have successfully fabricated the nitrogen-doped cuprous oxide thin films on the amorphous standard soda-lime glass by reactive high-power impulse magnetron sputtering. The energ…
