The object of this project is to carry out far infrared magnetospectroscopic studies of compound semiconductors. The emphasis is primarily on diluted magnetic semiconductors (DMS), i.e., on semiconducting alloys whose lattice is made up in part of substitutional magnetic ions. The program consists of four distinct but inter-related parts: far infrared study of the epitaxial layers and superlattices of the diluted magnetic semiconductors; magnetospectroscopy of DMS; magnetoadsorption by impurities in DMS; and the study of the effect of photon momentum on the dielectric response function in compound DMS. This grant has been transferred to the University of Notre Dame since the principal investigator, Professor Furdyna, has changed institutions.

本课题的目的是开展化合物半导体的远红外磁谱研究。重点主要是稀释磁性半导体（DMS），即半导体合金，其晶格部分由取代磁性离子组成。该计划由四个不同但相互关联的部分组成：稀释磁性半导体外延层和超晶格的远红外研究；DMS磁谱学；DMS中杂质的磁吸附；研究了光子动量对复合DMS介质响应函数的影响。由于首席研究员Furdyna教授换了机构，这笔拨款已经转移到圣母大学。
