Beyond graphene: atomic scale structure of quasi-2D van der Waals materials

ORAL

Abstract

Graphene, a single atomic layer of graphite, has attracted much attention for its unique electronic and mechanical properties. But what role does reduced dimensionality play in other 2D atomic crystals? In this talk we present scanning tunneling microscopy (STM) measurements of the atomic scale structure and spectroscopy of related quasi-2D materials including the transition metal dichalcogenides (TMDs), and their heterostructures with graphene.
