Design of a multiple ring Aharonov-Bohm gradiometer

Francesco Banfi

Risultato della ricerca: Contributo in rivistaArticolo in rivistapeer review


A novel semiconductor structure serving as a nanometre-sized gradiometer is proposed. The device relies on four concatenated Aharonov-Bohm rings, three of them lying on mutually perpendicular planes. Conductance oscillations due to magnetically induced electron wavefunction phase shift allow us to access information on the concatenated magnetic field with respect to all the device's planes. The feasibility of the device fabrication and potential applications are discussed.
