摘要：

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