Welcome to Prof. Kai Liu's group. The research in our group revolves around interface engineering of low-dimensional electronic materials and their applications in intelligent devices. We are pursuing creative, systematic, and high-impact work in this research field, and aiming to bridge fundamental physics studies to smart device applications (e.g., artificial synaptic devices and sensors). The explored materials include 2-dimensional (2D) layered materials, 1D carbon nanotubes, and vanadium oxides.
