Abstract

An in-plane magnetic field suppresses the quantum coupling between electrons in a double-quantum-well structure. The microscopic theory of this effect is developed and confirmed experimentally. We have shown that the decrease of the resistance resonance peak is sensitive to the mutual orientation of the current and the in-plane magnetic field. The characteristic field required for the suppression of the resonance depends on the elastic-small-angle and electron-electron scattering rates. The study of the characteristic field allows us to verify the temperature and Fermi-energy dependence of the electron-electron scattering rate, providing another experimental tool for its determination.
