Description
Conductance G of a 2DEG-superconductor (S) device in a high magnetic field is studied: G(ν) is calculated where ν is the filling factor. When the cyclotron diameter in 2DEG is larger than the width of the 2DEG-S surface then G(ν) 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 ν
Abstract (Russian)
Изучается проводимость G устройства 2DEG-сверхпроводник (S) в сильном магнитном поле. Рассчитывается зависимость G(ν), где ν - коэффициент заполнения. Когда циклотронный диаметр в 2DEG становится больше ширины поверхности 2DEG-S, то G(ν) становится немонотонной функцией вследствие интерференции квазичастиц типа Ааронова-Бома. При определенных параметрах перехода проводимость G осциллирует с νAdditional details
