|Title:||Coupled electron and phonon transport in one-dimensional atomic junctions||Authors:||Lü, J.T.
|Issue Date:||16-Oct-2007||Citation:||Lü, J.T., Wang, J.-S. (2007-10-16). Coupled electron and phonon transport in one-dimensional atomic junctions. Physical Review B - Condensed Matter and Materials Physics 76 (16) : -. ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevB.76.165418||Abstract:||Employing the nonequilibrium Green's function method, we develop a fully quantum mechanical model to study the coupled electron-phonon transport in one-dimensional atomic junctions connecting to one-dimensional leads. This model enables us to study the electronic and phononic transport on an equal footing. We derive the electrical and energy currents of the coupled electron-phonon system and present a self-consistent picture of energy exchange between them. As an application, we study the heat dissipation in current-carrying atomic junctions with metallic and semiconductor leads. We find that the inclusion of phonon transport is important in determining the heat dissipation and temperature change of the atomic junctions. © 2007 The American Physical Society.||Source Title:||Physical Review B - Condensed Matter and Materials Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/96120||ISSN:||10980121||DOI:||10.1103/PhysRevB.76.165418|
