Technical: The objective of the project is to explore fundamental materials behavior in ultra-scaled low-dimensional binary/ternary phase-change chalcogenide nanostructures. Aiming at generating in-depth knowledge for developing future-generation information technologies using nanoscale phase-change systems, the project is composed of two major parts: (i) exploitation of multi-level phase transition behavior in one-dimensional chalcogenide nanowires, discovering mechanism and technology pathway towards ultra-high-density information processing in future electronic systems, and (ii) investigation of ultimate materials scalability and energy efficiency in binary/ternary chalcogenides with deeply-scaled physical dimensions. Combining multiple Co-PI's different technical expertise, the team plans to build up comprehensive understandings of phase-change phenomena in aggressively scaled materials systems using both experimental and computational approaches with strong support from industry partner. The concept of information technology based of phase-change behavior in materials is recognized as one of the most successful innovations in microelectronics industry in this decade, leading to a prospective main-stream post-silicon technology. If successful, the proposed research would bring in substantial impact in this important technology by generating largely demanded knowledge to break through the well recognized technical barriers: power-efficiency and scalability.Non-technical: The research opens opportunities for graduate and undergraduate students to acquire interdisciplinary research experience in nanoscale sciences, material engineering, nanofabrication, and computational nanotechnology. The efforts broaden participation of under-represented groups in research programs at the two universities. Outreach activities comprise on-site demonstration of nanoscale scientific and engineering techniques for K-12 students in the Tech Valley of upstate New York and the greater Seattle Area. The dissemination of research results by journal publications and presentations at international conferences, and its inclusion in new curriculum development at both universities will ensure broad impacts to scientific, educational, and general public communities.

技术：该项目的目的是探索超级低维二进制/三元/三元相变的基本材料行为。为了生成深入的知识，以使用纳米级相变系统来开发未来的生成信息技术，该项目由两个主要部分组成：（i）在一维chalcogenide nanowires中剥削多级相位过渡行为，发现机制和技术途径在未来电子系统中的超高密度信息处理，以及（ii）研究具有深度缩放物理尺寸的二进制/三元/三元硫酸盐的终极材料可扩展性和能效。该团队将多个Co-Pi的不同技术专业知识结合在一起，计划在行业合作伙伴的大力支持下，使用实验和计算方法来积极地缩放材料系统中对相变现象的全面理解。基于材料中相位变化行为的信息技术的概念被认为是这十年中微电子行业最成功的创新之一，从而导致了前瞻性的主流后硅技术。如果成功的话，拟议的研究将通过产生大量要求的知识来突破公认的技术障碍：发电效率和可扩展性，从而对这项重要的技术产生重大影响。没有技术：这项研究为研究生和本科生提供了机会纳米级科学，材料工程，纳米制作和计算纳米技术方面的跨学科研究经验。努力扩大了代表性不足的群体在两所大学的研究计划中的参与。外展活动包括纳米级科学和工程技术的现场演示，适用于纽约州北部技术谷和大西雅图地区的K-12学生。杂志在国际会议上的出版物和演讲来传播研究结果，以及在两所大学的新课程开发中的纳入研究结果，将确保对科学，教育和公共社区的广泛影响。
