Nontechnical description:This interdisciplinary research project focuses on the synthesis of new materials which have a high electrical conductivity for small wires. This is important because more powerful and energy-efficient computers require smaller wires to connect the switches (transistors) as well as the memory elements. The key idea is to use a new type of materials for which electrons cannot be scattered at the wire surfaces. The project discovers such new materials and develops methods for their synthesis and integration into computer chip manufacturing, facilitating more powerful and energy-efficient chips used in devices ranging from smartphones to large data centers. The project includes a multifaceted education and workforce development initiative, involving education leaders from Historically Black Colleges and Universities and Minority Serving Institutions, scientists from research intensive universities, and development engineers from companies in the semiconductor industry. These initiatives are designed to increase diversity, quality, and quantity of the USA-based semiconductor chip manufacturing workforce. Technical description:This project aims to control the synthesis of new high-conductivity electrical interconnect materials and to co-design the conductor materials with the back-end dielectric to achieve a conductivity advantage over existing Cu technology in future integrated circuits. This involves exploiting scattering-immune surface transport in topological metals, tuning their Fermi level through strain and dielectric engineering for maximum topological effects, and achieving crystal orientation/chirality control for high conductivity in topological and anisotropic metals. The project uses a tight integration of complementary novel synthesis methods, high-throughput characterization, ab-initio electron transport calculations, as well as strain, dielectric and contact engineering. More specifically, it includes synthesis of topological and directional interconnect conductors using complementary techniques to prototype several classes of materials for the future semiconductor industry, co-design crystal growth orientation and chirality with electron transport to leverage favorable conduction including scattering-immune unidirectional surface transport in Weyl semimetals, and tuning of the Fermi level to Weyl nodes by elastic strain.This project is co-funded by the Historically Black Colleges and Universities Undergraduate Program (HBCU-UP), which provides awards to strengthen STEM undergraduate education and research at HBCUs.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术描述：该跨学科研究项目的重点是合成针对小电线的高电导率的新材料。这很重要，因为更强大，更节能的计算机需要较小的电线来连接开关（晶体管）以及内存元素。关键的想法是使用一种新型的材料，该材料不能散布在电线表面上。该项目发现了这种新材料，并开发了将其合成和集成到计算机芯片制造中的方法，从而促进了从智能手机到大型数据中心的设备中使用的更强大和节能的芯片。该项目包括一项多方面的教育和劳动力发展计划，涉及历史悠久的黑人学院和大学的教育领导者以及为机构提供服务的机构，研究密集大学的科学家以及半导体行业公司的开发工程师。这些举措旨在增加基于美国的半导体芯片制造业人士的多样性，质量和数量。技术描述：该项目旨在控制新的高导电性电气互连材料的合成，并与后端电介质共同设计导体材料，以在未来的集成电路中获得比现有CU技术的电导率优势。这涉及利用拓扑金属中的散射 - 免疫表面转运，通过应变和介电工程来调整其费米水平，以最大程度地拓扑效应，并实现晶体方向/手性控制，以在拓扑和各向异性金属中进行高电导率。该项目使用互补的新型合成方法，高通量表征，Ab-Initio电子传输计算以及应变，介电和接触工程的紧密整合。 More specifically, it includes synthesis of topological and directional interconnect conductors using complementary techniques to prototype several classes of materials for the future semiconductor industry, co-design crystal growth orientation and chirality with electron transport to leverage favorable conduction including scattering-immune unidirectional surface transport in Weyl semimetals, and tuning of the Fermi level to Weyl nodes by elastic strain.This project is由历史悠久的黑人学院和大学本科课程（HBCU-UP）共同资助，该课程为HBCUS提供了奖励，以加强STEM本科教育和研究。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评估评估来通过评估来获得支持的。
