There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
The objective of the proposed research is the modeling and the design of energy-efficient and scalable novel spintronic devices. Over the past two decades, spintronic devices have achieved special status due to their advantages in terms of low-voltage operation, smaller footprint area, non-volatile memory, and compatibility with CMOS technology. To design efficient spin-based systems, researchers require the precise modeling of the physics of nanomagnets, piezoelectrics, thermal noise, and metallic nanowires. Using the models developed during the research, spintronic logic devices comprised of hybrid magnetic and piezoelectric structures are proposed. The delay, energy dissipation, and footprint area of the proposed devices are analyzed. Moreover, the proposed devices are used as building blocks to propose spin-based logic gates, pattern and image recognition circuits, long-range interconnects, interface circuits, and coupled-oscillators. The performance of the proposed circuits is benchmarked against CMOS and other spin-based circuits, which shows improved performance, especially in implementing non-Boolean applications and interface circuits.
