US-Poland Joint Fund Research on Physics and Technology of Semimagnetic Semiconductors (MSC)

在这个项目中，华沙波兰科学院物理研究所的R.R. Galazka博士将与圣母大学的j.k Furdyna博士在美国-波兰Marie Sklodowska-Curie联合基金下合作研究“半磁半导体的物理与技术ıSMSC!”或半导体合金，其晶格部分由取代磁性原子组成。研究人员将重点关注：(1)Fe-based SMSC （II-VI晶体主体中带电子与Fe++之间的sp-d交换相互作用；Fe++能级相对于材料带结构的位置）；(2)涉及IV-VI宿主的SMSC（允许的能带结构；磁性离子之间的交换相互作用；能带结构和载流子浓度对材料磁性能的影响）；(3) SMSC中的局部化现象（供体和受体水平；受体波函数的形状；自旋相关现象；磁场诱导的半导体-金属Mott跃迁）。这个凝聚态物理项目通过使美国和波兰的顶尖专家在平等、互惠和互利的基础上，在共同感兴趣和能力强的领域结合互补的努力和能力，实现了推进科学知识的计划目标。

In this project, Dr. R.R. Galazka of the Institute of Physics, Polish Academy of Sciences, Warsaw, will cooperate with Dr. J.K. Furdyna of the University of Notre Dame under the U.S.-Poland Marie Sklodowska-Curie Joint Fund to research "Physics and Technology of Semimagnetic Semiconductors ıSMSC!," or semiconducting alloys whose lattice is composed in part of substitutional magnetic atoms. The researchers will focus on: (1) Fe-based SMSC (sp-d exchange interaction between band electrons and Fe++ in a II-VI crystal host; the position of Fe++ level with respect to the band structure of the material); (2) SMSC involving IV-VI hosts (band structure of the allows; the exchange interaction between magnetic ions; the influence of band structure and carrier concentration on magnetic properties of the materials); and (3) localization phenomena in SMSC (donor and acceptor levels; the shape of the acceptor wave functions; spin-related phenomena; magnetic-field-induced semiconductor-metal Mott transition). This project in condensed matter physics fulfills the program objectives of advancing scientific knowledge by enabling leading experts in the U.S. and Poland to combine complementary efforts and capabilities in areas of strong mutual interest and competence on the basis of equality, reciprocity, and mutuality of benefit.
