Suppression of Impurity Back Scattering in Double Quantum Wires: Theory Beyond the Born Approximation

PDF Version Also Available for Download.

Description

The effect of higher-order corrections to the Born approximation is studied for the previously obtained giant conductance enhancement in tunnel-coupled double quantum wires in a parallel magnetic field. The relative correction is found to be significant and depends on various effects such as the magnetic field, electron and impurity densities, impurity positions, symmetric and asymmetric doping profiles, and center barrier thickness.
