Welcome to
Dr. Jun YAN WEBSITE
Dr. Yan is now a tenure-track assistant professor at The Chinese University of Hong Kong, Shenzhen. He received his B.Eng. in 2012 and Ph.D. in 2018 under the supervision of Prof. Hongbin Wu and Prof. Yong Cao both at South China University of Technology. He was a key member in Prof. Jenny Nelson’s group in Department of Physics at Imperial College London between 2017 and 2022. His research focuses on using combined theoretical and experimental approaches to understand the device and molecular physics of organic molecular semiconductor devices, e.g. photovoltaics, light-emitting-diodes, and photodetectors.
My group focuses primarily on the physics of molecular electronic materials and devices, and is particularly interested in device physics and modelling, with an ambition to connect molecular properties to device properties. Our approach is to use combined theoretical and experimental findings to reveal the physical mechanisms behind organic electronic materials and devices and eventually facilitate the development and commercialization of organic optoelectronics.
