Linear and nonlinear dynamic conductivity of carbon nanotubes

Electronic properties of carbon nanotubes are studied. L inear response of dynamic conductivity of both zigzag and armchair nanotubes is analyzed at different temperatures and for different radii of nanotubes in the framework of semiclassical theory. Simpliˇ ed approach is used by introducing the mo...
