Geminate radiative recombination in GaAs/AIGaAs quantum-well structures in magnetic field
Kop'ev P. S. , Mirlin D. N., Sapega V. F., Sirenko A. A.
An appearance of a secondary emission band near the laser excitation line has been observed in GaAs/AlGaAs quantum-well structures in a magnetic field applied in the direction perpendicular to the plane of the layers. This emission is a consequence of a geminate recombination of electron-hole pairs.
