Low-Energy Conductivity of Single- and Double-Layer Graphene from the Uncertainty Principle
arXiv:0903.2766 · doi:10.1088/0031-8949/81/03/035702
Abstract
The minimum conductivity value as well as the linear dependence of conductivity on the charge density near the Dirac point in single and doublelayer graphene is derived from the energy-time uncertainty principle applied to ballistic charge carriers.
