Abstract

We have studied the temperature and magnetic field dependence of the luminescence of a two-dimensional electron system in the extreme magnetic quantum limit. Analysis of the intensity variations of the shoulder that appears on the low-energy side of the lowest Landau level luminescence peak, attributed to the formation of a pinned Wigner crystal, has enabled us to construct an electron solid phase diagram. In the fractional quantum Hall regime, we observe clear maxima in the high- and low-energy halfwidths of the luminescence line around fractional occupancies 1/3, 1/5 and 1/7. This behaviour is consistent with a transition between two luminescence lines at the shifts.
