Dr. Sun’s research group fosters interdisciplinary research including diverse topics of physics, chemistry and engineering of nanostructured materials. The goal of his research team is to discover and investigate the novel physical and chemical properties of the materials in the nanometer scale, and apply them in photochemistry, bio-imaging, light-emitting devices and solar cells.
Dr. Sun’s publication includes one paper in Nature Nanotechnology, one paper in Physical Review Letters, and six papers in Nano Letters. His PbSe-nanocrystal-based solar cells rank among the highest performing nanocrystal-based solar cells reported to date. His record-brightness PbS-nanocrystal-based light-emitting diodes emit infrared light with tunable wavelength from 800 nm to 1800 nm, which will find broad application in free space and fiber optical communication, night vision and sensing.
