On December 10th, Prof. Qihua Xiong from Nanyang Technological University visited Suzhou Institute of Nano-Tech & Nano-bionics, Chinese Academy of Sciences (SINANO) invited by Prof. Liwei Chen, and make a report named “Laser Cooling of Semiconductors: II-VI Nanoribbons and Organic-Inorganic Perovskite Crystals”.
Prof. 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 group has demonstrated for the laser cooling of II-VI semiconductors, which opens up a new territory of designing materials for the laser cooling of semiconductors with strong electron LO phonon coupling. Prof. Qihua Xiong’s excellent works gave a deep impress on the Researchers and the graduated students attended the lecture.
Biography:
Qihua Xiong, engineering, Ph.D., doctoral supervisor, professor of Nanyang Technological University. He graduated from the department of Wuhan University in 1997 and obtained M.S. in Physics at Shanghai Institute of Applied Physics (SINAP), Chinese Academy of Sciences in 2000. In 2006, he obtained Ph.D. in Materials Sciences at The Pennsylvania State University with the thesis advisor: Professor Peter C. Eklund. From 2006 to 2009, he was as a postdoctoral research fellow at Harvard University, with Professor Charles M. Lieber. From 2009 to 2014, he was a Nanyang Assistant Professor at School of Physical and Mathematical Sciences, School of Electrical and Electronic Engineering in Nanyang Technological University. Since March 2014, he became a Nanyang Associate Professor. His group at NTU recently focuses on the following areas: 1, develop novel approaches to synthesize and tune 1D nanomaterials and heterostructures; 2, Investigate their fundamental properties as an outcome of confined geometry and anisotropy; 3, Explore the applications of nanomaterials in nanoelectronics, nanophotonics, energy harvesting (solar and thermoelectricity); 4, Laser cooling of semiconductors and optical refrigeration; 5, Build nanoelectronic-bio interfaces, e.g., nanopore and nanopore field effect transistors for biosensing and engineered metamaterials structures for biosensing. He has published papers on Nature Photonics, Nature Nanotechnology, Nature Communications, Appl. Phys. Lett., Nano Lett., ACS Nano., Adv. Mater., Small, Sci. Rep., etc.
