Yonghui Zhang

Yonghui Zhang received the bachelor’s degree from the Hebei University of Technology in 2007, the master’s degree from the Beijing University of Technology, and the Ph.D. degree from the Institution of Semiconductors, Chinese Academy of Sciences, in 2015. After his Ph.D., he began teaching and research work at the Hebei University of Technology. He has published more than 20 articles related to these fields in international mainstream journals, and holds 6 patents. 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.
