This Focused Research Group (FRG) project the topic of length scales and dimensionality cross-over in nanoscience and technology. The project aims to bridge the gap between the nanoscopic world of atoms and the mesoscopic world of materials and devices, by integrating quantum growth with more traditional growth concepts, addressing a spectrum of fundamental issues in condensed matter- and materials sciences. The project addresses the size effect on (i) Cooper pair formation and order parameter in superconductivity; (ii) magnetic anisotropy and ordering tem-peratures in magnetic quantum dots; and (iii) the interplay between free carriers and magnetic moments in artificially-structured dilute magnetic semiconductors. The FRG involves researchers with complementary expertise and capabilities in quantum growth and manipulation schemes for metallic nanostructures, interface engineering, transport measurements on surface systems and ultrathin films, and theory of nucleation and growth, mesoscopic physics, transport, and magnet-ism. The project includes collaborative partnerships between the university investigators and the Center for Nanophase Materials Sciences (CNMS) at Oak Ridge National Laboratory (ORNL). %%% This project addresses basic research issues in a topical area of materials science with significant technological relevance, and places emphasis on the integration of research and education. The proposed program embodies development for a new partnership between the Center for Nano-phase Materials Sciences (CNMS) at Oak Ridge National Laboratory (ORNL) and the academic institutions represented in this proposal. The proposed science and supporting infrastructure pro-vide an excellent setting for the education and training of internationally competitive students and postdocs. They can access some of the world's most advanced facilities for nanoscale sci-ence and ultrafast computing at UT-Austin, UT-Knoxville, and ORNL. The educational outreach effort will focus on the development of a new curriculum for nanoscale science and technology, in partnership with the Center of Nano- and Molecular Science and Technology at the University of Texas. The curriculum will be aimed at bridging the departmental boundaries and traditional research disciplines, which is expected to foster a collaborative atmosphere of excitement and discovery. The research integrates materials synthesis and characterization, and shows how the-ory and experiment can work hand-in-hand to push the frontier of nanoscale science and technol-ogy. The project will enlarge the pool of young scientists who have collaborative research ex-perience and who will be ready to take their place in the highly-skilled workforce that continues to drive today's high-tech society. ***

这个重点研究小组（FRG）将纳米科学和技术的长度尺度和维度交叉的主题提出了主题。该项目旨在通过将量子增长与更传统的增长概念相结合，解决凝结物问题和材料科学中的基本问题，来弥合纳米镜世界与材料和设备的介绍世界之间的差距。该项目解决了（i）库珀对形成和秩序参数的尺寸影响； （ii）磁量子点中的磁各向异性和订购温度； （iii）自由载体与人工结构稀释磁性半导体中的磁矩之间的相互作用。 FRG涉及具有互补专业知识和能力的研究人员，用于量子生长和操纵方案，用于金属纳米结构，界面工程，表面系统和超薄膜上的运输测量以及成核和生长理论，介肠镜物理学，运输和磁性。该项目包括大学调查人员与橡树岭国家实验室（ORNL）的纳米材料科学中心（CNM）之间的合作伙伴关系。 %% %%该项目解决了具有重要技术相关性的材料科学主题领域的基础研究问题，并强调研究和教育的整合。拟议的计划体现了橡树岭国家实验室（ORNL）的纳米相材料科学中心（CNM）与本提案中代表的学术机构之间建立新合作伙伴关系的发展。拟议的科学和支持基础设施促成基础设施是对国际竞争学生和博士后的教育和培训的绝佳环境。他们可以在UT-AUSTIN，UT-KNOXVILLE和ORNL上访问一些世界上一些最先进的设施，并在UT-AUSTIN上进行纳米级规范和超快计算。教育外展工作将重点介绍与德克萨斯大学纳米和分子科学技术中心合作的纳米级科学和技术新课程。该课程将旨在弥合部门界限和传统研究学科，这有望促进兴奋和发现的协作氛围。该研究将材料的综合和表征整合在一起，并展示了如何与纳米级科学和技术形式的边界进行手工运作的方式。该项目将扩大拥有合作研究的年轻科学家的库，并准备在继续推动当今高科技社会的高技能劳动力中占据一席之地。 ***
