Abstract

The effective mass approximation is used to consider plasma and magnetoplasma waves in electron system on the surface of the cylindrical semiconductor nanotube. The electron-electron interaction is taken into account within the framework of the random phase approximation. In the case of degenerate electron gas the spectral windows on the wavevector-frequency plane and the spectra of the waves are obtained. Their frequencies undergo quantum oscillations of the de Haas-van Alfven type which are attributed to the Fermi level traversing the sub-zone boundaries in the electron energy spectrum. The spectrum and the damping of waves in the non-degenerate electron gas were found. In a magnetic field parallel to the cylinder axis the frequencies of the magnetoplasma waves undergoes the Aharonov-Bohm type oscillations appearing with changing magnetic field strength.
