Dirac Fermions at Interfaces

Investigating the electronic states of 2D Dirac surfaces, and their interaction at interfaces with other materials (magnetic, dielectric). These surfaces exist in materials like graphene, the layered material that makes up a graphite pencil, and a new class of materials called topological insulators that are like metallic wrapping of a chooclate block. By interfacing these materials with other layers, new enhanced phases of electronic behavior can emerge. I demonstrate that adding layers to graphene adds "good vibrations", and can reduce overall vibrational resistance.
