Research Content & Progress:
Aiming at the new rule and new effect of semiconductor functional quantum structure, we especially study dependence and variation regularity of semiconductor functional quantum structure’s function and structure, develop new structures, achieve new functions, and research new devices. It concretely include s five projects: (1) Regulation principle and device applications for band of wide bandgap semi-conductor induced by polarization, polarization properties of wide bandgap semiconductor, regulation principle and device realization for band of semiconductor functional quantum structure by polariza-tion; (2) Spin quantum structure and device of high curie temperature, origin for the ferromagnetism of wide bandgap diluted magnetic semiconductor, stable methods of getting high curie temperature diluted magnetic semiconductor, and spin quantum device; (3) Effect and regulation of semiconductor quantum structure spin splitting, internal connection of quantum confinement structure and spin splitting, effect of strain, and effects of band spin splitting such as spin photocurrent; (4) Functional coordination and device application of semiconductor composite quantum structure, preparing new semiconductor som-posite quantum structure, and investigating the functional coordination relation of composite quantum system; (5) Preparation and characterization of new type quantum dot nanostructure, investigating con-trollable growth and preparing of new type quantum dot structure such as sparse quantum dot and quan-tum dot molecule, studying the coupling effect of quantum dot electronic state and optical micro cavity.
