Rise of exciton luminescence of GaAs in a magnetic field
Zhilyaev Yu. V. , Rossin V. V., Rossina T. V. , Travnikov V. V.
An anomalously large (nearly 20-fold) increase in the intensity of exciton luminescence, has been discovered in magnetic fields up to 7 T. It is suggested that the effect stems from an influence of the magnetic field on the kinetics of excitons.
