Energy relaxation for hot Dirac fermions in graphene and breakdown of the quantum Hall effect
- Abstract:
-
Energy loss rates for hot carriers in graphene are experimentally investigated by observing the amplitude of Shubnikov-de Haas oscillations as a function of electric field. The carrier energy loss in graphene follows the predictions of deformation potential coupling going as ∼T4 at carrier temperatures up to ∼100 K, and that deformation potential theory, when modified with a limiting phonon relaxation time, is valid up to several hundred Kelvin. Additionally we investigate the breakdown of th...
