Welcome to the Jun Zhu Lab at Penn State

We are a condensed matter experimental group that focuses  on the exploration of fundamental and novel electronic properties of low-dimensional materials and their nanostructures. Our current research interests include two-dimensional layered materials such as graphene and transitional metal chalcogenides. We are interested in manipulating the multiple internal electronic degrees of freedom of the materials to explore the formation of collective phenomena, such as the quantum Hall and fractional quantum Hall effects in a strong magnetic field, and the emergence of one-dimensional chiral and helical edge states as a result of topology. We employ surface functionalization, interface engineering and complex device structures to engineer new properties and device functionalities in layered materials and their heterostructures. Please browse the current and past research topics for more details and contact us if you are interested in joining the lab or starting a collaborative project.
