Research Interests

Research in the Zhu lab focuses on the exploration of fundamental and novel electronic properties of low-dimensional materials and nanostructures. Our current research interests include two-dimensional layered materials such as graphene, atomically thin metals, and new van der Waals compounds. We are interested in controlling the interaction, competing electronic degrees of freedom, and the topology of 2D materials to explore emergent quantum phenomena in 1D and 2D systems. We employ van der Waals stacking, interface engineering and advanced nanofabrication techniques to engineer new material structures and device functionalities. We use low-temperature transport and strong magnetic field to investigate the ground state and collective excitations of many-body systems.
