Abstract: A model of spontaneous formation of the core-shell structure in (In,Ga)As nanowire grown via molecular beam epitaxy without independent radial growth is proposed. Within the framework of the proposed model, the distribution of In across the axis of the nanowire was fitted.

Keywords: core-shell nanowire, ternary nanowire, InGaAs nanowire, radial nanowire heterostructure.
