1. Curvature-Induced Energy Band Tilting in Finite-Length Carbon Nanotubes
Master-uppsats, Institutionen för fysikSammanfattning : The near-Fermi-energy energy band structure of carbon nanotubes is given by cross-sections of the graphene Dirac cones near the K and K' points. Using second-order perturbation theory and a nearest-neighbor approximated tight-binding model, curvature-induced corrections to the graphene-based effective model are derived. LÄS MER
