Magneto-electric effect in non-uniform quantum nanotube

[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.
