摘要：
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, G(nu) becomes a nonmonotonic function, owing to the Aharonov-Bohm-type interference of quasiparticles at the surface. At certain parameters of the junction, the conductance oscillates with nu. (C) 2001 MAIK "Nauka/Interperiodica".
