Feng-Qi Liu Male, born in Aug. 1963. Winner of National Science Fund for Distinguished Young Scholars. Researcher and tutor of Ph.D.graduate students. Received the M.S. degree in solid state physics from University of Science and Technology of China, in 1990, and the Ph.D.degree in condensed matter physics from Nanjing University, in 1996. His research has focused on MBE technology, semiconductor nano-materials and devices, quantum cascade lasers, semiconductor clusters design and assembly. He has developed strain-compensated InGaAs/InAlAs quantum cascade lasers operating at 3.5 microns above room temperature, and has achieved several significant results in strain-compensated InGaAs/InAlAs quantum cascade lasers operating at 5.5 and 7.8 microns and GaAs/AlGaAs quantum cascade lasers operating at 9.1 microns. He disclosed the existence of quasifree clusters by a novel experimental design, and realized the cross-over of self-organized quantum dot array into quantum wire. He presented a route to realize a high resolution nanograting woven by strain-compensated self-assembled semiconductor nanowires.
