Published values for the room temperature thermal conductivity of graphene vary from ~2000 W/m*k to 5600 W/m*k, for freely suspended samples. The large discrepancy shows the sensitivity of graphene to lattice defects (contact with substrate, edge defects, etc.)
Thermal conductivity increases as temperature decreases, until about 100K, where it drops due to increased umklapp scattering. Doped graphene, or graphene with vacancies, has been shown to have some unique properties, and this is where my interest lies.
At low temperature, thermal transport is dominated by the lattice, with very little electronic contribution (>10%) My question; what happens to the lattice when graphene is subjected to a magnetic field? Graphene with vacancies has shown some very interesting magnetic properties, and would undoubtedly be effected in a magnetic field.
Curious as to your thoughts on this.
