Research Interests

Aiming Yan’s research focuses on atomic-/nano-scale structural and property tailoring, and in-situ/operando study of functional materials via combined synthesis and advanced microscopy approaches. She is especially interested in precise structural design of atomically thin two-dimensional materials by using a state-of-the-art in-situ transmission electron microscope that is equipped with a sub-Angstrom electron beam. This effort enables further exploration of novel electrical and magnetic properties hosted in these nano- even atomic-sized local structures. Another main research direction Aiming is pursuing is to develop new material synthesis techniques based on chemical/physical vapor deposition methods to create novel two-dimensional materials and heterostructures with emerging physical properties.
