What is Graphene Force-Constant Model for Conductivity about?
The document presents a force-constant model of graphene to calculate phonon-limited electrical conductivity. The model aims to reproduce density functional theory (DFT) calculated phonon frequencies and modes using a 4 nearest-neighbor force-constant model. This will incorporate long-range interactions in graphene. The model shows that DFT phonon modes approach canonical modes in the long wavelength limit, but exhibit acoustic-optical mixing at finite momentum that is linear in the magnitude of the wavevec
