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 کاملHalf-metallic properties of KP compound in a bulk and (001) surface of rock-salt structure: A b-initio study
Given the many applications of half-metals in the spintronics devices, we investigated the half-metallic properties of the KP compound in rock-salt (RS) and cesium chloride (CsCl) structural phases by using density functional theory. The results indicated that the KP compound as the half-metal in the RS structure, in contrast to the CsCl structure, due to the small lattice constant and failure ...
متن کاملLaboratory measurements of the optical properties of sea salt aerosol
The extinction spectra of laboratory generated sea salt aerosols have been measured from 1 µm to 20 µm using a Bruker 66v/S FTIR spectrometer. Concomitant measurements include temperature, pressure, relative humidity and the aerosol size distribution. The refractive indices of the sea salt have been determined using a simple har-5 monic oscillator band model (Thomas et al., 2004) for aerosol wi...
