Electromagnetic field emitted by core–shell semiconductor nanowires driven by an alternating current

We consider tubular nanowires with a polygonal cross-section. In this geometry the lowest energy states are separated in two sets, one of corner and side-localized states, respectively. The presence an external magnetic field transverse to nanowire imposes additional localization mechanism, electrons being pushed sideways relatively direction field. This effect has important implications on current density, as it creates loops induced by Lorentz force. calculate numerically electromagnetic radiated hexagonal, square, triangular nanowires. demonstrate that, because aforementioned properties, can have complex distribution determined internal nanowire. suggest that measuring neighborhood could be basic idea tomography electron inside it, if smaller receiver antenna placed zone.
