Magnetoresistance and Hall effect in tunneling-coupled quantum wells with asymmetric scattering
A semiclassical description of the energy spectrum is not valid for tunneling-coupled quantum wells whose relaxation times rl and rr are different, because the 2X2 Green's function cannot be diagonalized in the case т{фтг. Quantum-mechanical expressions are accordingly derived for the magnetoresistance and the Hall effect even in weak magnetic fields {ω0τΐ Γ < 1, where <oc is the cyclotron frequency).
