Graphene under pressure: Raman and resistive measurements to 40 GPa
ORAL
Abstract
Two-dimensional (2D) materials, such as graphene, offer a variety of outstanding properties for a wide range of applications. The exemplary 2D material, graphene, continues to provide a wealth of interesting physics. In this talk we present novel experimental methods that allow us to study this unique material within a diamond anvil cell to high pressure. Using these experimental methods, we present combined Raman spectroscopic data and direct resistivity measurements on pure monolayer graphene up to 40 GPa at room temperature. With simple physical models we are able to extract effective 3D stiffness parameters from the 2D graphene, and relate these parameters to the observed resistances.
