Intensities of quantum transitions in hexagonal nanotubes within the exciton spectral range

Abstract

The theory of exciton spectrum and intensities of interband quantum transitions in multi-shell hexagonal semiconductor nanotube is developed within the effective masses and rectangular potentials approximations using Bethe variational method. The obtained theoretical results well explain the experimental position of luminescence peak for As Ga GaAs/Al x 1 x  nanotubes.

Spectral parameters of electron in multi-shell open semiconductor nanotube

“…The multi-shell semiconductor nanotubes have been recently studied both theoretically and experimentally [1][2][3][4][5][6][7]. The unique properties of quasi-particles (electrons, excitons and so on) in these nanostructures allow using them as basic elements for the devices of modern nanoelectronics [8][9][10].…”

“…The theory of exciton and phonon stationary spectra together with the theory of electron-and exciton-phonon interaction well correlating to the experimental data and general physical considerations is already developed for the closed cylindrical and hexagonal nanotubes [5][6][7].…”
