Conductance of a Semiconductor-Superconductor junction in high magnetic field

Abstract

Conductance $G$ of a 2DEG-Superconductor (S) device in a high magnetic field is studied: $G(\nu )$ is calculated. When the cyclotron diameter in 2DEG is larger than the width of the 2DEG-S surface then $G(\nu )$ becomes nonmonotonous function due to the Aharonov--Bohm type interference of quasiparticles at the surface. At certain parameters of the junction the conductance oscillates with $\nu$.
