Magneto-conductance of hybrid quantum ring

Magneto-conductance behaviors of hybrid magnetic-electric quantum rings are studied. The hybrid magnetic-electric quantum rings are formed by spatially in-homogeneous distributions of magnetic fields and the additional antidot electrostatic potential. Electrons are both magnetically and electrostatically confined to the plane. Electronic structures of hybrid magnetic-electric quantum rings and two terminal conductance taking into account the resonant backscattering via the magnetic edge channels are shown including comparison with the case of a conventional electric quantum ring with uniform external magnetic field.
