About this book
This book highlights the origin of low external quantum efficiency for deep ultraviolet light-emitting diodes (DUV LEDs). In addition, it puts forward solutions for increasing the internal quantum efficiency and the light extraction efficiency of DUV LEDs. The book chiefly concentrates on approaches that can be used to improve the crystalline quality, increase carrier injection, reduce the polarization-induced electric field within multiple quantum wells, suppress the TM polarization emission, and enhance the light escape from the semiconductor layer. It also demonstrates insightful device physics for DUV LEDs, which will greatly benefit the optoelectronic community.

Dr. Yonghui Zhang received his Bachelor’s and Master’s degrees from Hebei University of Technology in 2007 and Beijing University of Technology, respectively. After earning his Ph.D. from the Institution of Semiconductors, Chinese Academy of Sciences in 2015, he began teaching and research work at Hebei University of Technology. His main research interest is in GaN-based light emitting diodes (LEDs) with micro- or nano-structure. In this regard he is employing a range of nanotechnologies, including nano-patterned sapphire substrate, photonic crystal and core-shell technology, to improve the quantum efficiency of LED. He has published more than 20 papers related to these fields in international mainstream journals, and holds six patents.
