PURPOSE: Electronic portal imaging devices (EPIDs) are increasingly used for IMRT dose verification, both pretreatment and in vivo. In this study, an earlier developed backprojection model has been modified to avoid the need for patient-specific tran

An analysis of the fraction of strongly localized excitons (FSLE) for a number of InGaN/GaN quantum wells emitting from violet to green, as a function of temperature, and a number of wells grown under the same conditions is reported. The analysis is

An analysis of photoluminescence (PL) spectra for a range of single and multiple InGaN/GaN quantum wells, as a function of temperature, is presented. The well-known anomalous 'S-shape' behaviour is observed for samples emitting over a very wide range

Analysis of the phonon sidebands (PSB) observed in the photoluminescence (PL) spectra from a series of InGaN/GaN multi-quantum wells is described. The structures are grown by metal organic vapour phase epitaxy (MOVPE) on sapphire substrates and cover

In this paper, we describe the growth and characterization of InGaN single quantum wells with emission peaks in the blue, green, amber and red spectral regions, grown by metal-organic vapour phase epitaxy. Starting from the growth of a blue-emitting

The use of lateral overgrowth techniques to develop III-nitride microcavities with both mirrors fabricated from very highly reflecting dielectric multilayers (e.g. SiO2/ZrO2) will be discussed. Multilayer mirror stacks with broad high reflectivity st
