Electronic states in cylindrical core-multi-shell nanowire

Abstract

The recent advances in nanowire (NW) growth technology have made possible the growth of more complex structures such as core-multi-shell (CMS) NWs. We propose the approach for calculation of electron subbands in cylindrical CMS NWs within the simple effective mass approximation. Numerical results are presented for $GaAs/A{\mathrm{l}}_{0.3}\mathrm{G}{\mathrm{a}}_{0.7}\mathrm{As}$ radial heterostructure with AlGaAs-core and 4 alternate GaAs and AlGaAs shells. The influence of an effective mass difference in heterolayers is discussed.
