Mildred Dresselhaus Prize in Nanoscience or Nanomaterials Winner: Eva AndreiAtomically thin crystals: a myriad electronic incarnations viewed through STM*

The discovery of atomically thin crystals has transformed the way we think about materials. Following the discovery of the first atomically thin crystal, graphene, this family of materials has rapidly grown to include dozens of viable two-dimensional (2D) crystals, with thousands more predicted theoretically. Like an alchemist’s toolbox, the 2D structure makes it possible to alter a material’s electronic properties, without changing its chemical composition, by using alternative means such as introducing strain patterns or superposing layers with a twist between their crystal axes. In this talk I will describe highlights of this rapidly evolving field with emphasis on results obtained from scanning tunneling microscopy and spectroscopy.
