U.S.-Czech Materials Research on Low-Dimensional Electronic Systems in Semiconductors

INT 9602140 MacDonald 这个美国-布卢明顿的印第安纳州大学的艾伦·麦克唐纳博士和捷克物理研究所的帕维尔·斯特雷达博士之间的捷克材料研究项目将以与低维电子系统相关的基本物理为特色。 具体来说，研究人员将通过关注零磁场和倾斜磁场中的双层系统来研究多层电子系统的平衡和传输特性。 这项合作将建立在飞机间运输的理论基础上，捷克团队试图定义层间相关性如何反映电荷在观察到耦合效应的两层之间分配的方式。 结果预计将导致多层系统的电子结构进行面内磁场的测定，并有助于一个理论，可以描述在存在的磁场，施加平行或倾斜的层平面的面内运输。 这种关于磁阻的新知识在制造半导体器件时可能是有用的。 该材料研究理论项目通过使美国和东欧的专家能够联合收割机互补人才并在相互感兴趣和能力强的领域共享研究资源，实现了推进科学知识的计划目标。 ??

INT 9602140 MacDonald This U.S.-Czech materials research project between Dr. Allan MacDonald of Indiana University, Bloomington, and Dr. Pavel Streda of the Czech Institute of Physics will feature the basic physics associated with low-dimensional electron systems. Specifically, the researchers will study equilibrium and transport properties of multi-layer electron systems by focussing on double-layer systems in zero and tilted magnetic fields. The collaborative effort will build upon theories of inter-plane transport as the U.S.-Czech team attempts to define how the inter-layer correlations reflect the way the charge is partitioned between two layers where coupling effects are observed. Results are expected to lead to a determination of the electronic structure of multi-layer systems subjected to in-plane magnetic fields and to contribute to a theory that can describe in-plane transport in the presence of a magnetic field, applied parallel to or tilted from the layer plane. Such new knowledge of magnetoresistance may prove useful in fabricating semiconductor devices. This project in materials research theory fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Eastern Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence. ??
