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

到目前为止，逻辑电路，因此它们实现的计算电子系统，主要是用cmos(互补金属氧化物半导体)晶体管来实现的。在过去的几十年里，CMOS技术的进步导致了电子系统的能力和复杂性的显著进步。随着我们达到这一进步的物理极限，我们需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。这个项目探索使用电子的磁性状态，而不是总电子电荷的典型测量，来定义代表信号信息的逻辑状态。由于磁性状态以前仅用于构建存储器或存储器件，因此其在逻辑电路中的应用要求本项目探索和共同优化新型磁性器件和结合它们的新电路技术。通过与业界的直接合作，上述新型器件和电路可以在半导体行业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，这是匹兹堡的一个非营利性组织，设计初中和高中项目，利用创业学习和商业创造来吸引年轻人参与学习。这项工作的技术方面将作为一个平台，扩大磁学在初中、高中和本科大学课程中的覆盖面。

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.
