Research Interests

​Dr. He puts all his efforts in the development of transparent and flexible electronics using novel devices based on nanomaterials, including solar and photo-detector, LED, and memory devices. He is also interested in harsh electronics, where he has a particular interest in solar energy are efforts to understand light scattering and trapping in nanostructured materials and design next-generation solar cells. He is also interested in transport of charge carriers across these solar cells and improving light coupling to increase the efficiency of photo-induced charge separation. Dr. He's group is also currently involving in fundamental physical properties of the nanomaterials, such as the transport and switching behavior of 2D nanomaterials.
