Abstract

The π-electronic collective excitations (π plasmons) in carbon nanotube bundles are studied within the linear-response approximation. The intertube Coulomb interactions significantly affect the electronic excitations, so that the π plasmons in nanotube bundles are quite different from those in a single nanotube. The π plasmons strongly depend on the direction and magnitude of the transferred momentum. They clearly exhibit the anisotropic behavior. Moreover, the π plasmon frequencies are lower for bundles made up of larger nanotubes.
