Dr. Dean leads an experimental condensed matter physics laboratory at Columbia University in the city of New York. He studies novel 2D materials for a wide range of multidisciplinary efforts with collaborations across Physics, Electrical and Mechanical Engineering, Opto-electronics, Chemistry and even Biology.
Join us for a reception prior to the talk at 3:30pm in STC 0050
Graphene, a single layer of carbon atoms arranged in a hexagonal lattice, is probably the best known, and most extensively characterized two-dimensional material. However, this represents just one of a larger class of van der Waals materials, in which atomic monolayers can be mechanically isolated from the bulk. By integrating these materials with one another, an exciting new opportunity has emerged in which layered heterostuctures can be fabricated with properties beyond those of the constituent materials. In this talk I will present some of our recent efforts where, by tuning the geometry of these heterostructures at the nanoscale, we are able to realize yet a new level of control over their electronic properties.
