Wigner crystallization in a two-dimensional electron gas under high magnetic fields was predicted (and was observed experimentally) to occur for small filling factors (less than ν ν = 1 / 5 ) of the lowest Landau level. For larger fractional fillings, the Wigner crystal was thought to be unstable relative to the fractional quantum Hall effect (FQHE) liquid states. A Wigner crystal was observed in the immediate neighborhood of the large fractional filling ν ν = 1 / 3 , and led to a new understanding (based on the pinning of a rotating Wigner molecule) for the interplay between quantum-liquid and pinned-solid phases in the lowest Landau level.
