Infrared and Raman spectra of the quartz, rutile and amorphous forms of GeO2 have been recorded under pressure and/or temperature, in order to study the crystalline to crystalline - or amorphous - transformations of this compound in the solid state. X-ray ...
The intensity distributions in the overtones of resonance Raman spectra for I2 in liq. CCl4 and Xe are presented for several excitation energies in the bound part of the B 3P0u+ state. In liq. CCl4, the decrease in intensity with v" is monotonous and for ...
A hexagonal two-dimensional model of particles with displacive degrees of freedom and interacting via potential energy with harmonic and anharmonic third- and fourth-order terms has been studied by the molecular-dynamics technique. The modulated phases cha ...
The rates of combination of Me. with NO and O2 were measured by flash spectroscopy at 295 DegK. The highpressure rate coeff. for Me. + NO(+M) -> MeNO(+M) was recorded as 1.0(+-0.15) * 1013 cm3 mole-1 sec-1. The low-pressure fall-off was interpreted with th ...
Junctions between n-type semiconductors of different electron affinity show rectification if the junction is abrupt enough. With the advent of 2D materials, we are able to realize thin van der Waals (vdW) heterostructures based on a large diversity of ma ...
