Semiconductors and Microelectronics Technology Seminar - Kyung Min Kim, Thursday, April 10th at 1:30pm in EEB 248

Speaker: Kyung Min Kim, Associate Professor, Materials Science and Engineering Korea Advanced Institute of Science and Technology (KAIST)

Talk Title: Spatiotemporal Computing Utilizing Dual Thermal Dynamics of Mott Memristors

Series: Semiconductors & Microelectronics Technology

Abstract: The Mott memristor is a highly intriguing device that demonstrates unique electrical characteristics through the dynamic interaction of heat and current. The device exhibits dynamic thermal behavior, encompassing temporal accumulation via heat capacity and spatial transportation through heat diffusion. This spatiotemporal thermal activity enables coupling between memristor devices when arranged in arrays, which can be effectively utilized for computing. Additionally, the thermal dynamics of Mott memristors inherently involve stochasticity, resulting in probabilistic behavior. These properties, such as thermal coupling and stochasticity, provide a novel approach to tackling NP-hard problems, which are often challenging for conventional computers to solve. This presentation explores various computing devices that leverage the spatiotemporal thermal information of Mott memristors, including true random number generators (TRNGs), probabilistic computing systems, and thermal computing devices. The future potential and implications of these technologies will also be discussed.
