Optical Studies of Semiconductors, Semiconductor Multiple Quantum Well Structures and Energy Transfer of Electronic and Molecular Defects in Ionic Crystals

这项研究计划在半导体的皮秒时间分辨拉曼研究，半导体多量子阱(MQW)结构和离子晶体中电子和分子缺陷的能量转移方面进行了研究。程序分为三个子程序：(1)半导体和半导体MQW结构中光激电子-空穴等离子体(EHP)的输运性质，(2)半导体MQW结构中电子-声子和声子-声子相互作用和深杂质，(3)碱金属卤化物中电子和分子缺陷的瞬时能量转移。

This research program is in the areas of picosecond time-resolved Raman studies of semiconductors, semiconductor multiple quantum well (MQW) structures and energy transfer of electronic and molecular defects in ionic crystals. The program is divided into three sub-programs: (1) transport properties of the photoexcited electron-hole plasma (EHP) in semiconductors and semiconductor MQW structures, (2) electron-phonon and phonon-phonon interactions and deep impurities in semiconductor MQW structures, and (3) transient energy transfer of electronic and molecular defects in alkali halides.
