Ballistic thermal rectification in nanoscale three-terminal junctions
arXiv:1003.5030 · doi:10.1103/PhysRevB.81.100301
Abstract
We study ballistic thermal transport in three-terminal atomic nanojunctions by the nonequilibrium Green's function method. We find that there is ballistic thermal rectification in asymmetric three-terminal structures because of the incoherent phonon scattering from the control terminal. With spin-phonon interaction, we also find the ballistic thermal rectification even in symmetric three-terminal paramagnetic structures.
