EAGER: Preliminary Studies on Novel Four-Terminal Spin Transfer Torque Devices to Enable All-Magnetic Logic Circuits

逻辑电路，也就是它们所支持的计算电子系统，迄今为止主要是用CMOS（互补金属氧化物半导体）晶体管实现的。在过去的几十年里，CMOS技术的进步导致了电子系统能力和复杂性的显著进步。当我们达到这一进步的物理极限时，有必要探索激进的新技术和相应的电路，以便在未来实现类似的进步。该项目探索使用电子的磁性状态，而不是典型的总电子电荷测量，来定义表示信号信息的逻辑状态。由于磁性状态以前仅用于构建内存或存储设备，因此其用于逻辑电路需要本项目探索和共同优化新型磁性设备和包含它们的新电路技术。通过与工业界的直接合作，上述新型器件和电路可以在半导体工业中实现新的电子产品和市场。此外，还计划与创业青年（www.eyouthamerica.org）合作。创业青年是匹兹堡的一个非营利组织，负责设计初中和高中课程，利用创业学习和商业创造来吸引年轻人学习。这项工作的技术方面将作为一个平台，以扩大磁学在初中，高中和本科大学课程的覆盖范围。

Logic circuits, hence the computational electronic systems that they enable, have to date been implemented primarily with CMOS (complementary metal oxide semiconductor) transistors. The improvement in CMOS technology for the past several decades has led to remarkable progress in electronic system capabilities and complexity. As we reach the physical limits of this progress, there is a need to explore radical new technologies and corresponding circuits that will enable similar progress in the future. This project explores the use of magnetic state of electrons, rather than the typical measure of total electron charge, to define the logic states that represent the signal information. Since magnetic state has previously been used only to construct memory or storage devices, its use for logic circuits requires this project to explore and co-optimize novel magnetic devices and new circuit technologies that incorporate them.Through direct collaboration with industry, the aforementioned novel devices and circuits could enable new electronic products and markets in the semiconductor industry. Furthermore, collaboration is planned with Entrepreneuring Youth (www.eyouthamerica.org), a nonprofit organization in Pittsburgh that designs middle school and high school programs that use entrepreneurial learning and business creation to engage young people in learning. The technical aspects of this work will be used as a platform to expand the coverage of magnetics in the middle schools, high schools and undergraduate college curriculums.
