Metal-insulator transition in two dimensional systems
Dr. Michael Osofsky
Materials Physics and Chemistry Section
Naval Research Laboratory, Washington, DC, U.S.A.
Recently, there has been an explosion of research in two-dimensional materials such as graphene, MoS2, and other transition metal dichalcogenides. These systems exhibit conventional metallic behavior which contradicts the prediction of Abrahams, Anderson, Licciardello, and Ramakrishnan that all two-dimensional systems must be insulating.1 In this talk, I will present an introduction to the concepts of localization in disordered materials and the results of electronic transport studies of two 2D systems, graphene and 10-30 nm thick films of RuO2, that exhibit both metallic and 2D insulating behaviors. These results show the universality of these behaviors and suggest a new way to describe the 2D metal-insulator transition.
