Enhanced Thermoelectric Power in Graphene: Violation of the Mott Relation by Inelastic Scattering
Enhanced Thermoelectric Power in Graphene: Violation of the Mott Relation by Inelastic Scattering
We report the enhancement of the thermoelectric power (TEP) in graphene with extremely low disorder. At high temperature we observe that the TEP is substantially larger than the prediction of the Mott relation, approaching to the hydrodynamic limit due to strong inelastic scattering among the charge carriers. However, closer to …
