✦ Synopsis

Upon decreasing the density, the 2D electron system exhibits a transition from the metallic state, characterized by the Quantum Hall effect, to the collective insulating state (electron solid), interrupted by the Quantum Hall effect at integer fdling factors v = 1, 2, and 6. The electron solid shows many features attributed to the pinned Wigner crystal. On the basis of the longitudinal and Hall resistance measurements through these reentrant transitions, we discuss the pathway for the disappearance of delocalized states.
