Determination of the Coulomb gaps under the conditions of fractional quantum Hall effect by the magnetoluminescence method
The results of an analysis of the spectral position curves of the luminescence line, which were measured experimentally and calculated theoretically, are presented. The luminescence line corresponds to a radiative recombination of 2D electrons with the holes at a neutral impurity center in a 5-doped AlGaAs/GaAs heterostructure under the conditions of fractional quantum Hall effect. The Coulomb gaps are determined.
