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.
