Abstract
I will present results on electronic transport between graphene and metallic contacts. Aluminum and Copper tunnel junctions have been fabricated, and preliminary work on Gold point contacts will be discussed. The study of such interfaces is important for the integration of graphene into existing electronics as well as the development of new devices.
Speaker bio
I received my B.S. from the University of Wisconsin - Madison. I was lured to Condensed Matter physics by superconductors, where quantum mechanics could be macroscopic in size, I stayed because of the sheer scope of its importance. Most of human history has been demarcated by materials, the Bronze age, the Iron age, the age of Steel, and the Silicon age (the age of Steam is a gas, you can't win them all); the understanding and use of new materials has often been transformative to say the least. Now I study exfoliated graphene, ripped by scotch tape from deep inside a piece of graphite, itself born in immense temperatures and pressures inside the earth. I try to find how this exciting electronic material interacts with more familiar metals such as aluminum, copper, and gold.
