报告题目：3-D integration of multifunctional ZnO for renewable energy applications

报告人：Professor Yicheng Lu
Department of Electrical and Computer Engineering, Rutgers University
报告摘要
ZnO is a promising wide band gap semiconductor. It also has been emerging as an important multifunctional oxide material. Single crystal ZnO nanotips are grown on various substrates, including Si, GaN, glass, and metals. The ZnO nanotips exhibit dominant free excitonic transition and enhanced luminescence efficiency. A 3-D electrode technology is developed by integrating a 2-D ZnO based transparent conductive oxide (TCO) film with 1-D ZnO nanotips array by sequential MOCVD growth plus the in-situ doping control. We have integrated ZnO based multi-layers and nanostructures to construct novel devices for the system on glass (SOG), in particular, for the renewable energy applications. Control of the dimension and morphology of the ZnO-based photoelectrode in conjunction with energy band engineering enable to improve the performances of various types of solar cells. The same 3-D ZnO electrode technology also significantly enhances the GaN LED’s photon extraction. The recent progress on the ZnO 3-D integration for novel applications, including reconfigurable SOG, sensor and biochip on SOG, will also be discussed.
