Laser-Induced Reactive Deposition of Nanostructured CoS2- and Co2CuS4-Based Films with Fenton Catalytic Properties

Highly polymorphic cobalt sulfide represents attractive material because of its unique electronic, optical, magnetic, mechanical and catalytic properties. Pulsed laser irradiation of a solid CoS2 target results in ablation and deposition of thin films on Ta and Cu substrate, which were analy...

Possibilities of Increasing the Usability of Sputtered AZO Films as a Transparent Electrode

Aluminum-doped zinc oxide (AZO) is a promising candidate to replace ITO film as transparent electrode. Due to its lower price it is applied in the production of silicon solar cells, however, it is difficult to obtain suitable electrical properties at low deposition temperatures. Mo...

Derivative optical spectroscopy of thin films of alkaline-earth titanates: Critical points

This paper analyzes UV Vis absorption spectra of thin films of alkaline-earth titanates (BaTiO3, SrTiO3 and BaSrTiO3) deposited by RF magnetron sputtering on SiO2 at different substrate temperatures. The Tauc procedure was used to determine optical band gaps for direct and indirect inte...

Signature of a highly spin polarized resonance state at Co2MnSi (0 0 1)/Ag (0 0 1) interfaces

We investigated interfaces of halfmetallic Co 2 MnSi(1 0 0) Heusler thin films with Ag(1 0 0), Cr(1 0 0), Cu and Al layers relevant for spin valves by high energy x-ray photoemission spectroscopy (HAXPES). Experiments on Co 2 MnSi samples with an Ag(1 0 0) interface&...

Effect of graphite felt properties on the long-term durability of negative electrode in vanadium redox flow battery

In our contribution we study the long-term durability of two different graphite felt materials serving as negative electrode in vanadium redox flow battery. Both electrodes differ in the precursor material and the way of activation which causes significant differences in relevant properties&...
