Abstract
We review the results of our study of the properties of the magnetic field induced insulating phase in a two-dimensional electron gas in modulation-do ped In0.53Ga0.47As/InP heterostructures. The experiments were performed in the millikelvin range of temperatures in very high magnetic fields. The res ults can be explained by the assumption of the formation of a glassy Wigner solid.
