We report on a magneto-luminescence on a double quantum well subject to an in-plane magnetic field. The attention is paid to the properties of interwell excitons, which are indirect in the real space and which become indirect in the reciprocal space as well when a finite in-plane magnetic field is applied. Such indirect exciton states become optically inactive unless some relaxation mechanisms of...
We report on low-temperature magneto-luminescence measurements of biased Ga1-xAlxAs/GaAs double quantum well structures. The luminescence of spatially indirect excitons (IX) is studied up to the magnetic field of 22T. In contradiction to theoretical predictions and their several experimental confirmations, the IX line survives in PL spectra of our double quantum well structure up to high in-plane...
