点击翻译按钮获取中文摘要

Global warming warrants urgent investment in clean and sustainable energy generation. This project aims to investigate the use of nitride semiconductors, a commonly used material for LEDs, and solar energy to generate hydrogen by splitting water molecules. These semiconductors have excellent light absorption efficiency and can be designed to better match the solar spectrum. The project will explore the underlying mechanism of light interaction with the semiconductor through band bending and surface engineering, and determine how this interaction affects the dissociation of water molecules. The concepts demonstrated in the project are expected to pave the way for further development of this technology for future applications.
