Query: Thermal and Thermoelectric Properties of Graphene   The subject of thermal transport at the mesoscopic scale and in
low-dimensional systems is interesting for both fundamental research and
practical applications. As the first example of truly two-dimensional
materials, graphene has exceptionally high thermal conductivity, and thus
provides an ideal platform for the research. Here we review recent studies on
thermal and thermoelectric properties of graphene, with an emphasis on
experimental progresses. A general physical picture based on the Landauer
transport formalism is introduced to understand underlying mechanisms. We show
that the superior thermal conductivity of graphene is contributed not only by
large ballistic thermal conductance but also by very long phonon mean free path
(MFP). The long phonon MFP, explained by the low-dimensional nature and high
sample purity of graphene, results in important isotope effects and size
effects on thermal conduction. In terms of various scattering mechanisms in
graphene, several approaches are suggested to control thermal conductivity.
Among them, introducing rough boundaries and weakly-coupled interfaces are
promising ways to suppress thermal conduction effectively. We also discuss the
Seebeck effect of graphene. Graphene itself might not be a good thermoelectric
material. However, the concepts developed by graphene research might be applied
to improve thermoelectric performance of other materials.
