Device Modeling and Circuit Design for Scalable Beyond-CMOS Computing

Emerging technologies provide potential solutions to overcome the limitations of modern CMOS technologies. Specifically, as power density limitations impede further CMOS scaling, emerging technologies including spintronics, memristors, ambipolar transistors, and other beyond-CMOS devices are promising replacements for conventional CMOS transistors due to features such as non-volatility, low energy consumption, high operation speed, or high logical expressiveness. Specifically, we have evaluated spintronic technologies such as domain wall-magnetic tunnel junctions (DW-MTJs) and magnetic skyrmions that are particularly exciting for highly-efficient non-volatile information processing. Additionally, we have explored unconventional electronic switching devices including ambipolar transistors and memristors as replacements to CMOS and for hybrid emerging technology-CMOS computing systems.
