Abstract:

Two-dimensional materials are some of the most fascinating materials currently under study with diverse electronic, optical and magnetic properties. Graphene is the most well-known and developed of these materials with a current barrier being the production of large-area electronic grade doped material. In this talk I will review some of our work on the large area production of doped graphene at low temperatures and also discuss how graphene could be used to breach the THz gap for new types of sources, detectors and antennas. Beyond single layer graphene, layer-stacking plays an important role in the electronic properties and I will show how it is possible to introduce bandgap into bilayer graphene. Elemental layered materials are not just confined to carbon, I will also discuss some of our research on silicene (single layer silicon) and germanene highlighting the similarities and differences to graphene.
