This Inter-American Materials Collaboration brings together two groups led by Giovanni Zangari at the University of Virginia and Wagner Figuereido at the Universidade Federal de Santa Catarina, Florianopolis, Brazil. The project focuses on studies of the electrochemical growth, structural and functional characterization of magnetic metals and selected alloys on semiconductors. The electrochemical growth of single metals on Si and III-V semiconductors with various orientations is first studied leveraging existing work by the two groups. This is followed by studies of the growth and properties of technologically relevant alloys. Electrochemical techniques and a wide array of structural and physical characterization methods are utilized to tailor growth conditions for the production of films with optimum properties.In parallel, theoretical models of the electrochemical growth of these materials are developed and theoretical parameters in the model are determined by comparison with experimental results.This research program includes two Ph.D. students at each institution working on their own material system but interacting through the use of common methods and techniques and the need to solve similar problems. Close collaboration between the research groups is enhanced by the regular exchange of students between the two laboratories and periodical visits of the senior investigators to the foreign institution. The students are thus subject to different but integrated learning environments to which they also actively contribute. From the technical standpoint, this project provides a relevant contribution to the development of effective techniques for the direct integration of magnetic films with semiconductors, by creating useful knowledge, ready to be transferred to the industrial development and practice. This award is supported by the Division of Materials Research, the Office of International Science and Engineering, and the Office of Multidisciplinary Activities in the Directorate for Mathematical and Physical Sciences.

这项美洲材料合作项目汇集了由弗吉尼亚大学的 Giovanni Zangari 和巴西弗洛里亚诺波利斯圣卡塔琳娜联邦大学的 Wagner Figuereido 领导的两个小组。该项目重点研究半导体上磁性金属和选定合金的电化学生长、结构和功能表征。首先利用两个小组的现有工作，研究了具有不同方向的单金属在 Si 和 III-V 半导体上的电化学生长。接下来是技术相关合金的生长和性能的研究。利用电化学技术和各种结构和物理表征方法来定制生长条件，以生产具有最佳性能的薄膜。同时，开发了这些材料的电化学生长的理论模型，并通过与实验结果进行比较来确定模型中的理论参数。该研究计划包括两个博士生。每个机构的学生都在使用自己的材料系统，但通过使用共同的方法和技术以及解决类似问题的需要进行互动。两个实验室之间定期交换学生以及高级研究人员定期访问外国机构，加强了研究小组之间的密切合作。因此，学生们处于不同但综合的学习环境中，他们也积极地为之做出贡献。从技术角度来看，该项目通过创造有用的知识，为磁性薄膜与半导体直接集成的有效技术的开发做出了相关贡献，可随时转移到工业开发和实践中。该奖项得到了材料研究部、国际科学与工程办公室以及数学和物理科学局多学科活动办公室的支持。
