Abstract. The spectral parameters (resonance energies and resonance widths) of electron in multi-shell open cylindrical semiconductor nanotube are theoretically investigated within the effective mass and rectangular potentials model by using the S-matrix approach. These parameters as functions of the nanotube thickness and axial quasi-momentum are analyzed for the nanostructure composed of GaAs and AlxGa1−xAs semiconductors.

Keywords: nanotube, quasi-stationary state, resonance energy, resonance width.
