研究领域

OPTOELECTRONIC AND SPIN-OPTOTRONIC PROPERTIES OF LOW DIMENTIONAL MATERIALS INCLUDING MANY BODY INTERACTIONS Low dimentional materials including (quantum dots, nanowires/nanotubes, 2D materials) have highly tunable optical properties and stronger electron hole interactions comparing with 3D materials. We solve Bethe-Salpeter Equations (BSE) without explicit empty electronic states to treat e-h interactions explicitly[1-3] and optimize their optical properties by forming interfaces, introducing defects and surface functionalization. We study spin-defects in 2D materials for quantum information applications[4], focusing on their excited state lifetime and spin relaxation/decoherence mechanism. We develop charge correction methods that can provide reliable charged defect properties for 2D systems and general interfaces[4]. We develop methodology to compute exciton radiative[5] and nonradiative recombination rates[6] including electron-hole and electron-phonon couplings, and spin-lattice relaxation time through first-principles quantum dynamics for open systems[7].
