Iontronics and Nanoelectronics Lab at RIT
Our group develops energy-efficient AI hardware based on two-dimensional (2D) materials and iontronic (ion-controlled electronic) devices. We investigate ion–electron transport at the molecular level and exploit these dynamics to design devices that perform neuromorphic and time-dependent information processing, embedding computation directly in device physics. By controlling ion–electron interactions in 2D transistors, we enable real-time, low-power edge AI, bridging materials science, device physics, computer engineering, and artificial intelligence.
Dr. Ke Xu
Dr. Ke Xu is an Assistant Professor in the School of Physics and Astronomy and in Microsystems Engineering at Rochester Institute of Technology. Previously he was a Research Assistant Professor at University of Pittsburgh and Executive Director of the Pittsburgh Quantum Institute (PQI). He received his B.S. in Optical Engineering from Zhejiang University, China, and his Ph.D. in Electrical Engineering from University of Illinois at Chicago working with Dr. Michael Stroscio and Dr. Mitra Dutta. His doctoral research focused on graphene- and DNA aptamer-based micro/nano scale electronic devices and their applications in photo-detectors and biomolecular sensing. He worked as a post-doc researcher with Dr. Susan Fullerton-Shirey and Dr. Alan Seabaugh at University of Notre Dame on the development of low-voltage and steep subthreshold swing components for beyond-CMOS electronic systems.
The Xu Group
We are a highly multidisciplinary team that includes PhD students in Microsystems Engineering and Physics, MS students in Materials Science and Engineering and Physics, and undergraduate students in Chemical Engineering, Computer Science/Cybersecurity, and Physics.
