Lab Overview
Our research focuses on next-generation semiconductor devices for high-density and low-power electronics. We are particularly interested in (1) 3D integration, (2) semiconductor devices for next-generation computing, and (3) AI for semiconductor technology. Our work spans material, device, and system-level studies, aiming to enhance integration density and energy efficiency in electronic systems.
