Abstract

We study the radiative recombination of two-dimensional electrons in GaAsGaAlAs heterojunctions with holes localised on acceptors in strong magnetic fields. From the spectral position of the luminescence line, we derive values for the quasiparticle energy gaps of the Fractional Quantum Hall Effect. In the Wigner crystal regime, an additional luminescence line appears which shows an electric field threshold enhancement, characteristic of a pinned electron solid.
