Abstract
We review the results of our study of the properties of the magnetic field induced insulating phase in two-dimensional electron gas in modulation-doped In0.53Ga0.47As/InP heterostructures. The experiments were performed in the millikelvin range of temperatures in very high magnetic fields. The results can be explained by the assumption of the formation of a glassy Wigner solid. A model is proposed for the Wigner crystal-like ordering of the two-dimensional electron gas in this low-dimensional electron system with large disorder.
