In this study, dielectric properties of graded and non-graded InGaN/GaN multi quantum wells (MQWs), grown on sapphire(Al2O3) wafer by Metal Organic Chemical Vapor Deposition (MOCVD) technique, are investigated. order to notice layer effect characteristics MQWs some GaN layers doping atoms. Dielectric function films determined Swanepoel envelope method. Real imaginer coefficient the calculated u...

Abstract Using internal photoemission of electrons, the energy position valence band top edge in 1 monolayer WS 2 films on SiO thermally-grown Si was monitored to evaluate stability layer with respect two critically important technological factors: exposure air and transfer from growth substrate (sapphire) onto . Contrary previous results obtained for MoS layers synthesized by metal film therma...

The laser-driven MiniFlyer system is used to launch a small, thin flyer plate for impact on a target. Consequently, it is an indirect drive technique that de-couples the shock from the laser beam profile. The flyer velocity can be controlled by adjustment of the laser energy. The upper limits on the flyer velocity involve the ability of the substrate window to transmit the laser light without a...
