Xiong, Qihua - Nanyang Technological University - School of Physical and Mathematical Sciences

个人简介

Dr. Qihua Xiong is currently Nanyang Assistant Professor at Nanyang Technological University. He holds a joint appointment between School of Physical and Mathematical Sciences and School of Electrical and Electronic Engineering. Prior to joining NTU, he worked as a postdoctoral research fellow in the laboratory of Professor Charles Lieber at Harvard University. Dr. Xiong finished his B.S. degree in Physics at Wuhan University in 1997. After obtained his M.S. diploma in physics from Shanghai Institute of Applied Physics, Chinese Academy of Sciences (CAS) in 2000, he went to United States of American with a scholarship support to pursue his Ph.D. research. In 2006, he received his Ph.D. degree in materials science at The Pennsylvania State University under the supervision of Professor Peter Eklund. His thesis research work focuses on fundamental physical properties especially on phonon properties of semiconductor nanowires. During his postdoctoral training, he has extended his research to include high performance nanoelectronic devices based on one-dimensional electron gas in nanowire heterostructures and nanoelectronic devices for single molecule biosensing. Dr. Xiong received several awards and fellowships during his graduate and undergraduate studies, including Pan-American Advanced Studies Institute (PASI) fellowship (DOE and NSF, 2006), Graduate Award for Academic Excellence (The Pennsylvania State University, 2006), Excellent Graduate Fellowship Award (1998 and 1999, CAS), Hui Kai Fellowship Award (Wuhan University, 1996), Gui Zhiting-Xu Hailan Fellowship Award (Wuhan University, 1995) and Outstanding Student Award (Wuhan University, 1994). He won 2nd round Singapore National Research Foundation Research Fellowship in 2009 and chose NTU as the host institute to carry out his research.

研究领域

Dr. Qihua Xiong?s research is driven by the paradigm of ?bottom-up? nanoscience and nanotechnology. His research covers rational synthesis of functional semiconductor nanomaterials, systematic investigations on their physical properties at quantum size regime and practical applications in nanoelectronics, nanophotonics and nanobiotechnology. His expertise includes Raman scattering spectroscopy, optical absorption spectroscopy, electron microscopy and spectroscopy, scanning probe microscopy, electrical transport, photoconductivity and nanopore biosensing. His group at NTU recently focuses on the following subjects: Develop novel approaches to synthesize and tune 1D nanomaterials and heterostructures Investigate their fundamental properties as an outcome of confined geometry and anisotropy Explore the applications of nanomaterials in nanoelectronics, nanophotonics, energy harvesting Build nanoelectronic-bio interfaces, e.g., nanopore field effect transistor for biosensing
