Abstract

The electronic and transport properties of nanotube-ribbon hybrids subject to the influences of a perpendicular magnetic field are investigated theoretically. The energy dispersion relations are found to exhibit significant dependence on the nanotube-ribbon interactions, the field strength, and the geometry of the hybrids. Variations in the electronic structures with field strength or nanotube location will be reflected in the electrical and thermal conductance. The chemical-potential-dependent electrical and thermal conductances exhibit a stepwise increase and spike behavior. These conductances can be tuned by varying the field strength or the nanotube location. The peak and shoulder structures of the conductance will be stretched as temperature rises. In addition, quantum conductance behavior in nanotube-ribbon hybrids can be observed experimentally at temperature below 10 K.
