Exciton spectrum in multi-shell hexagonal semiconductor nanotube

Exciton spectrum in multi-shell hexagonal semiconductor nanotube

The theory of exciton spectrum in multi-shell hexagonal semiconductor nanotube is developed within the effective masses and rectangular potentials approximations using the method of effective potential. It is shown that the exciton binding energy for all states non-monotonously depends on the inner...
