摘要: Magnetoconductance (MC) injunctions of a superconductor and a semiconductor (Sm) consisting of two parallel quantum waveguides (QW) coupled through a potential barrier under a perpendicular applied magnetic field in the semiconductor region is studied theoretically. The results of MC showing a series of oscillations with stepwise platform and spikes may be understood well within the phenomenological argument similar to Y. Asano (Phys. Rev. B 61 (2000) 1732) proposed. The oscillatory peaks of the MC in the dual QW are found essentially due to the variation of the number of the propagation modes. (C) 2003 Elsevier Science B.V.
