    Abstract: The electronic and transport properties of nanotube-ribbon hybrids subject to the influences of
    a transverse electric field are investigated theoretically. The energy dispersion relations are found to exhibit
    rich dependence on the nanotube-ribbon interactions, the field strength, and the geometry of the hybrids.
    The nanotube-ribbon coupling will modify the subband curvature, create additional band-edge states, and
    change the subband spacing or energy gap. The bandstructures are asymmetric and symmetric about the
    Fermi energy when the interactions are turned on and off, respectively. The inclusion of a transverse electric
    field will further alter the bandstructures and lift the degeneracy of the partial flat bands in hybrid (IV).
    The chemical-potential-dependent electrical and thermal conductance exhibit a stepwise increase behavior.
    Variations in the electronic structures with field strength will be reflected in the electrical and thermal
    conductance. Prominent peaks, as well as single-shoulder and multi-shoulder structures in the electrical
    and thermal conductance are predicted when varying the electric field strength and the nanotube location.
    The features of the conductance are found to be strongly dependent on the field strength, the geometry
    and the temperature.
