Bio

Dr. Sun received his PhD in 2009 from the Institute of Physics, Chinese Academy of Science, Beijing. He did postdoctoral research at Oak Ridge National Laboratory from 2009 to 2011 and at the University of Utah from 2012 to 2014. He continued to work at the University of Utah as a research assistant professor from 2015 to 2016. He recently joined the NC State Department of Physics as an assistant professor.

Research Description

Dr. Sun’s research interests are in spintronics and optoelectronics of organic semiconductors, magnetic thin films and organic-inorganic hybrid perovskites. It includes the studies of organic spin valves, organic light-emitting diodes, hybrid perovskite optoelectronic/spintronics devices, and their device physics. The Sun Research Group at NC State focuses on exploring novel routes for spin injection and detection, magnetic field effect, spin Hall effect and their applications in molecules, polymers and newly emerged materials.
