Optical properties of wurtzite and rock-salt ZnO under pressure
This paper reports on the pressure dependence of the optical absorption edge of ZnO in the wurtzite and rock-salt phase, up to 14 GPa. Both vapor-phase monocrystals and pulsed-laser-deposition thin films have been investigated. In both types of samples the wurtzite to rocksalt transition is observed at 9.7G0.2 GPa. The absorption tail of the fundamental gap, as measured in monocrystals, exhibit...
متن کاملKinetics of the wurtzite-to-rock-salt phase transformation in ZnO at high pressure.
Kinetics of the wurtzite-to-rock-salt transformation in ZnO has been studied in the 5-7 GPa pressure range at temperatures below the activation of diffusion processes. The detailed analysis of non-isothermal experimental data using the general evolution equation describing the kinetics of direct phase transformations in solids allowed us to study the kinetic particularities of both nucleation a...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

We have investigated theoretically the thermoelectric effects in wurtzite GaN crystals and AlxGa1−xN alloys. The electron-transport model includes all dominant energy-dependent electron-scattering mechanisms, such as charged dislocation and ionized impurity scattering, polar optical phonon, deformation potential, and piezoelectric acoustic-phonon scattering. The results of the calculation show ...
