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…
Thermally-induced microstructural evolution in nanoparticle-based CuO, WO and CuO-WO thin films for hydrogen gas sensing
Kalyani Shaji, Stanislav Haviar, Petr Zeman +4
This study systematically investigates the microstructural evolution of nanoparticle-based CuO, WO, and composite 'CuO-WO' thin films induced by their post-deposition annea…
New polymorph γ-CuWO4 inspired by γ-CuMoO4: experimental identification and theoretical verification
Jiri Houska, Stanislav Haviar, Jiri Capek +4
In the context of our efforts to develop hydrogen gas sensors, two samples of ternary CuWO4 with the same crystalline structure have been prepared by two different non-equilibrium…
