Spectral parameters of electron in multi-shell open semiconductor nanotube

Abstract

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 quasimomentum are analyzed for the nanostructure composed of GaAs and Al x Ga 1-x As semiconductors.
