Associate Professor Department of Electrical and Electronic Engineering   Research Group

Dr. Shuming CHEN received his BS degree in optoelectronics from South China University of Technology (SCUT) in 2005. And then, due to his excellent academic record (2nd/55), he was admitted to the Department of Physics of Sun Yat-Sen University (SYSU) with exemption for entrance examination, where he obtained his ME degree in 2008. He then studied with Professor Hoi-Sing Kwok at Hong Kong University of Science and Technology (HKUST) and received his PhD degree in Electronic and Computer Engineering in 2012. From Sep. 2012-May 2013, he worked as postdoctoral researcher in Center for Display Research, HKUST and part time senior engineer in Sinodisplay Technology Co. Ltd. to develop active-matrix (AM) organic light-emitting displays (OLEDs). He officially joined the Department of Electrical and Electronic Engineering, SUSTech as an Assistant Professor in June 2013 and was promoted to tenured Associate Professor in Nov 2018.

His research interests include QLED, OLED, TFT and other novel (opto-)electronic devices and their application in Displays. He has published over 80 SCI papers on high impact journals including Nature Communications, Advanced Materials, Advanced Functional Materials, ACS Nano, Angewandte Chemie, Nano Energy with more than 5000 citations.

Personal Profile

Research

Quantum Dot Light-Emitting Diodes (QLED), Organic Light-Emitting Diodes (OLED) and their application in display and lighting.

Colloidal Quantum Dot Light-Emitting Diodes (QLED) have attracted considerable interests in recent years because of their advantages of high color saturation, tunable emission color and inherent high stability, which make them promising candidates for next generation displays. We focus on developing efficient and stable QLED devices through designing novel structures, engineering critical interfaces, studying device physics and developing novel fabrication processes.

Topics under investigation include:

Device Structures. Novel device structures such as microcavity, top-emitting, tandem, inverted, transparent, flexible, white-emission, light-coupling and etc.

Device Physics. Carrier injection and transport, charge balance, exciton dynamic, degradation mechanism, interfacial physics and etc.

Device Fabrication Techniques. Low-cost fabrication techniques including all-solution processing, ink-jet printing, transferring, laminating and etc.
