Sm. Badalian et al., THEORY OF AUGER UP-CONVERSION IN QUANTUM-WELLS IN A QUANTIZING MAGNETIC-FIELD, Journal of physics. Condensed matter, 5(36), 1993, pp. 6719-6728
Scattering rates of Auger and electron-phonon processes between discre
te Landau levels in a quasi-two-dimensional electron system are calcul
ated. Using these rates we provide an understanding of the upconversio
n observed in the magneto-luminescence of one-side modulation doped Ga
As/AlGaAs quantum wells; in particular, of its dependence on excitatio
n power and magnetic field.
