Exploring the Electronic Properties of Layered Materials

Abstract:

Layered materials such as graphite consist of two-dimensional molecular sheets held together by weak electrostatic forces. The weak interlayer binding makes it possible to separate the crystal into single molecular sheets. These two-dimensional crystals can have properties that differ significantly from the "mother crystal." Perhaps the most well-known of these two-dimensional crystals is graphene, formed by peeling away a single layer of graphite. Graphene in its purest state is strong, light, and an excellent conductor of heat and electricity. The seemingly limitless potential applications combined with the need to understand the fundamental physics have made graphene a superstar of condensed matter physics. This makes other layered materials jealous. As such, this colloquium will explore some of the other similarly structured materials that have been overlooked as well as several techniques used to study the electronic properties of crystals that are inherently lacking in the third dimension.
About the speaker:
Dr. Stollenwerk received a B.S. in physics and a B.A. in mathematics at Miami University in 2002. His graduate work was performed at the University at Albany SUNY, where he received his M.S. in physics in 2004 and his Ph.D. in Nanoscience in 2007. He joined the physics department at the University of Northern Iowa in 2009 after a two year postdoctoral fellowship at Harvard University studying single electron charging in colloidal quantum dots.
