RESEARCH INTEREST

Dr. Qihua Xiong’s research is motivated by the understanding of unprecedented properties of quantum matter. His research covers the rational synthesis of functional semiconducting nanomaterials, systematic investigations on their physical properties by steady-state and transient optical spectroscopy at quantum size regime and practical applications in nanoelectronics, nanophotonics and energy. His group is notable for recent achievement in realizing Van der Waals epitaxy growth of non-planar semiconductor nanostructures and perovskite crystals, fundamental investigations of lattice dynamics concerning surface modes in semiconductor nanowires and low-frequency shear and breathing modes in 2D layered materials, emission of excitons and their interactions with phonons, as well as demonstrating metamaterials plasmonic sensors and plasmonic nanolasers. Most recently, Dr. Xiong has ventured into the field of optical refrigeration leading to the breakthrough discovery of laser cooling of semiconductors and sideband Raman cooling of optical phonons.
