After pyrolysis at 800掳C, the Ni-NiO/N-C electrocatalysts were obtained and applied to HER. The XRD, SEM, TEM, BET, XPS and Raman spectroscopy were conducted to analyze the physical and chemical properties of the catalysts. Results show that the catalysts are present in ...
RamanNi silicides contacts, which are expected to be advantageous contact materials on SiC, were tested in this work. Prepared contact structures were ohmic with low contact resistivity approximately 8×10-4 Ω cm2 after annealing at 960°C as far as the SiC substrate with a medium doping ...
