Essay

At the base of the developed theory, the dependences of the electron, exciton and phonon spectra on the geometrical parameters of nanotube are studied. The relationship between the number of interface modes and the number of interfaces between semiconductor media in nanosystem is established. It is shown that the total shift of the quasi-particles energy level is formed by the electron (hole) interaction both with the confined and interface phonons and the respective magnitudes of the partial shifts are of the same order. It is established that in hexagon nanotube the location in the energy scale and the magnitudes of the intensities of experimental luminescence peaks correlate well with the theoretical data.
