  • Abstract
    We present a full band investigation of electron-phonon interaction in Graphene NanoRibbons (GNRs) by exploiting a tight-binding description within the deformation potential approximation. We show that a full band approach is required to obtain accurate results: mobility as high as 800 cm2/Vs at room temperature can be achieved for 1 nm-wide ribbons, more than one order of magnitude higher than that obtainable in silicon nanowires, but still not enough to ensure ballistic transport in GNR-based devices.
