Nitride nanowires for advanced optoelectronic and energy applications

点击翻译按钮获取中文摘要

Group III-nitride semiconductor devices, which are currently in widespread use in white, blue and green LEDs, and Bluray lasers, have a multi-billion dollar market. This project aims to address and improve the issues and challenges which still limit the true potential of these materials, by tailoring them at the nanoscale. Understanding the fundamental growth mechanisms of these nanowires and their structural, optical and electrical properties will allow precise and controllable synthesis of the nanowires to specific requirements. This will further allow demonstration of high efficiency UV LEDs, compact green/yellow lasers, nanowire solar cells and photoelectrodes for hydrogen generation from splitting water.
