The resonance Raman and far-infrared spectra of n -Bu 4 NI 3 show the coexistence of symmetrical ( C 2ν ) and unsymmetrical ( C s ) I 3 species, which are clearly distinguished by varying the wavelength of the excitation line. Only a slight deviation from D ∞ h symmetry has been ...
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 ...
