Graphene at the Boundaries
Thousands of researchers are investigating graphene's remarkable structural, mechanical, optical, and electronic properties. Most of these studies, however, have focused on only one of graphene's attributes at a time, neglecting its unique combination of properties. In this talk we will look at these interdisciplinary boundaries, examining cases when a mix of graphene's properties - electrical, thermal, optical, or mechanical-are simultaneously important.
For example, we will discuss experiments on graphene atomic membranes where electronic and optical signals can control the frequency, amplitude, and damping of a graphene drumhead resonance. We also present ultrafast measurements of photocurrent in graphene p-n junctions and explore the properties of a literal boundary that occurs in bilayer graphene. Finally, we will look at how graphene is likely the ultimate in flexible electronics.
