Low Dimensional Structures and Devices

这个为期三年的合作项目是基于1991年4月开始的文部省-SERC备忘录。本项目的主要研究内容包括：1）短周期超晶格的电子结构和性质; 2）调制掺杂量子威尔斯阱光谱中的多体效应; 3）低维半导体结构的磁光和磁输运研究; 4）LDSD中的量子霍尔效应和量子干涉现象; 5）半导体光量子阱中的量子干涉现象。5）晶体生长机制。除了对日本和联合王国的个别访问外，目前就上述主题开展的合作工作以独特的方式进行。也就是说，英国成员将SERC在英国LDSD项目中制作的良好样品带到东京大学固体物理研究所的Megagauss实验室，由英国和日本联合团队进行实验。并对实验结果进行了分析 ...更多信息 理论家和实验家在一个联合小组中发表演说。就这样，在日本和英国科学家之间创造了一种非常愉快的国际合作气氛。这种友谊使目前的合作工作非常成功，在三年期间取得了一些突出的成果。1992年10月8日，在英国内阁府组织的、在伦敦皇家学会举行的“英日科学技术交流会”上，该合作项目被选为两国间最成功的合作项目之一。由于目前的合作项目已取得了一些富有成效的成果，1993年8月30日和31日，由英国小组的首席代表兼联合代表John Walling博士和Paul Butcher教授在牛津郡阿宾登的SERC Coseners House举行了英国-日本15+15研讨会，在全体会议上讨论这些成果。为了讨论研讨会的计划以及如何总结目前关于LDSD的联合项目，日本首席代表Hiroshi Kamimura在研讨会之前于1993年2月访问了英国，并会见了John Walling和Paul Butcher。在讲习班上，每个与会者都注意到，目前的合作工作是以非常积极和开拓性的精神进行的。因此，日本和英国双方都认识到，增加两国之间的合作研究活动可能会带来互惠互利，因此取得了许多富有成效的成果。在这方面，英国和日本的成员都同意，我们应继续这项合作工作，确保取得进一步的杰出成就。少

This-three-year-collaboration project on LDSD based on the Monbusho-SERC Aide Memoire started on April of 1991. Main subjects in this collaboration program were the following : 1)Electronic structures and properties of short period superlattices ; 2)Many-body effects in the optical spectra of modulation doped quantum wells ; 3)Magneto-optical and magneto-transport studies of low-dimensional semiconductor structures with use of ultrahigh magnetic fields ; 4)Quantum Hall effects and quantum interference phenomena in LDSD ; 5)Mechanisms of crystal growth. The present collaboration work on the above subjects have been conducted in a unique way, in addition to individual visits to and from Japan and the UK. That is, the British members brought good samples made by the SERC projects on LDSD in the UK into the Megagauss Laboratory in Institute for Solid State Physics in the University of Tokyo to carry out experiments by a joint UK-Japan team. Then the results have been analysed by the collab … More oration of theorists and experimentalists in a joint team. In this way an extremely pleasant atmosphere of international collaboration has been created between Japanese and British scientists. This friendship has led the present collaboration work most successfully, and a number of outstanding results have been obtained during the three year period. As a result this collaboration work has been chosen as one of the most successful collaboration works between two countries in the "UK-Japan Science and Technology Event" which was organized by the British Cabinet Office and held in Royal Society in London in October 8th of 1992. Since a number of fruitful results have been obtained by the present collaboration projects, the UK-Japan 15+15 Workshop to discuss these results in a plenary session were organized by Dr. John Walling and Prof. Paul Butcher, chief representative and co-representative of the UK group and was held in the SERC Coseners House at Abingdon in Oxfordshire on August 30 and 31 of 1993. In order to discuss a program of the workshop and also how to summarize the present joint project on LDSD, Japanese chief representative, Hiroshi Kamimura visited the UK in February of 1993 prior to the workshop and met John walling and Paul Butcher. In the Workshop every participant has noticed that the present collaboration work has been conducted in a very positive and pioneering spirit. Consequently a number of fruitful results have been obtained, both Japanese and UK sides recognizing the mutual benefits which could result from an increase in collaboration research activities between the two countries. In this context both British and Japanese members have agreed that we should continue this collaboration work ensuring further outstanding achievements. Less
