Exciton spectrum in hexagon nanotube accounting exciton–phonon interaction

Spectral Parameters of Electron in a Multishell Semiconductor Cylindrical Nanotube with a Donor Impurity at Its Axis

“…Having found¯corresponding to the minimum Δ (¯) of functional (18), we obtain final expressions for the energy spectrum (16) and the wave functions (17) of an electron in the combined cylindrical semiconductor nanotube with a donor impurity.…”

“…The choice of a variational function for excited states is ambiguous and cumbersome [15]. Much more informative is the method of effective potential, which was used earlier for the theoretical study of the excitonic spectrum in simple and combined semiconductor nanotubes [7,17]. As far as we know, the issues concerning the interaction of the electron with the donor impurity in a combined multishell semiconductor nanotube have not been studied at all.…”

Exciton Spectra in Multi-Shell Open Semiconductor Nanotube

“…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]. The quasistationary spectra of electrons, holes and excitons were theoretically studied for the sphericallysymmetric quantum dots and single cylindrical quantum wires [13][14][15][16][17].…”

“…The multi-shell semiconductor nanotubes have been recently studied and experimentally [1][2][3][4][5][6][7]. The unique properties of quasi-particles (electrons, e in such nanostructures allow using them as basic elements for the de nanoelectronics [8][9][10][11][12]: nanosensors, tunnel nanodiodes, wavelength-cont effective solar energy conversion devices [8][9][10][11][12].…”
