Magnetoconductance Oscillations in Ballistic Semiconductor-Superconductor Junctions
arXiv:cond-mat/9909118 · doi:10.1103/PhysRevB.61.1732
Abstract
The mechanism of the magnetoconductance oscillations in junctions of a ballistic semiconductor and a superconductor is discussed. The oscillations appear when both the normal and the Andreev reflection occur at the interface. The interplay between the classical cyclotron motion of a quasiparticle and the phase shift caused by the magnetic field is the origin of the conductance oscillations.
