【 摘 要 】

A model of non-uniform core-shell type nanostructure with a donor located at a bottleneck point of the core is considered. It is shown that such structure can have a giant polarizability, which, besides can be controlled by applying of the external magnetic field. Presented theoretical analysis reveals a new possibility for the coupling between the polarization and magnetization arising from the quantum-size effect in non-uniform semiconductor nanowires.
