Abstract
Plasma dispersion relations of an electron gas on a tubule are obtained in the random phase approximation and the one dimensional limit. Intraband plasmon has a relationship between the plasma frequency ω p and the wavevector q of ω p∼q(|lnRq/2|) 1/2 , and the interband plasmon has a relationship ω p∼const. in the long wave length limit.
