Current Research Interests
The current research interests focus on synthesis and assemble of various nanocrytals for device applications: (1) Synthesize magnetic nanoparticles by chemical/physical methods and assemble them into ordered array for the potential applications in the next generation of data storage devices. (2) Synthesize/assemble chalcogenide nanocrystals by chemical methods and evaluate their photovoltaic, thermalelectric properties and process on their integration into devices. (3) Fundamental study on shape, phase, compostion and property control during nanocrystal synthesis.
He obtained his BS in Materials Science and Engineering, Nanjing University, 1999. He finished his Phd from Materials Science and Engineering Department of State University of New York at Stony Brook in 2004. After that, He joined the Materials Science and Engineering Department of Rensselaer Polytechnic Institute as a postdoctoral research associate until joining Nanyang Technological University in 2007.
