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 کاملUse of Strain Gages for Low Temperature Thermal Expansion Measurements
The use of strain gages for low temperature thermal expansion measurements is increasing, due to it's convenience, and relative accuracy. The determination of thermal expansion with strain gages is complicated by "thermal output strain", a phenomena caused by the temperature dependence of the gage. If thermal output strain is properly compensated , strain gages may be used to measure thermal ex...
متن کاملLOW TEMPERATURE MOLTEN SALT SYNTHESIS OF NANO CRYSTALLINE MgAl2O4 POWDER
Abstract: composition of MgO and nano boehmite. The reactant and potassium chloride, as the reaction media, were fired at800-1000 °C at different dwell times (0.5-5 h) in the ambient atmosphere. After washing and filtration, the spinel nanopowder was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) techniques. It was demonstrated tha...
متن کاملPART A: TEMPERATURE AND THERMAL EXPANSION The Use of 1-D Ocean Models to Estimate Global Temperature and Thermal Expansion
Following the general convention, we use a one-dimensional ocean model to simultaneously calculate transient air temperatures and thermal expansion of ocean water. We then employ subsidiary equations to estimate changes in sea ice and polar temperatures. After summarizing the results from our initial draft assumptions, we present the assumptions suggested by the expert reviewers and the resulti...
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...
