Abstract:
The radiative recombination time of spatially separated electron-hole layers has been investigated as a function of the magnetic field parallel to the plane of a wide quantum well. The luminescence intensity has been found to decrease with increasing parallel magnetic field. This dependence is inconsistent with the theoretical predictions relating the decrease in the intensity to a decrease in the population of the energy levels allowed for radiative recombination. It has been shown that the intensity decrease is related to the exponential increase in the radiative recombination time with the magnetic field (due to a decrease in the overlapping of the electron and hole wavefunctions) and to the nonradiative recombination processes.
