Our research focus on computational design and search for stable and controllable nano-sized semiconducting materials. Specifically, our research focuses on (i) the roles of defects, such as transition-metal and p-type dopants, in activating high Curie-temperature ferromagnetism; (ii) charge-transfer transitions for potential solar energy conversion; (iii) chemical and physical processes required to control magnetization using time-dependent quantum mechanical electrodynamics of charge-transfer delocalization, magnetic polaron formation, and magnetization reversal dynamics; and (iv) dopant-centered Auger-type processes and their role in the photodynamics of these doped nanocrystals.
