Abstract

We have studied coherent electron transport phenomena in tunnel-coupled quantum point contacts (QPCs) from double quantum well (QW) GaAs/AlGaAs- heterostructures. Here, we investigate the dependence of hybridizing subbands on an external magnetic field along the electron transport. Magnetotransport of coupled QPCs of two heterostructures with different tunnel barrier height has been recorded in a spectroscopic manner and shows an oscillatory behavior of coupling and decoupling. The magnetic field oscillation period does not depend on the height of the tunnel barrier.
