摘要：

We present magnetotransport results for strongly coupled p-type double quantum wells which demonstrate the existence of a correlated nu=1 quantum Hall state in the limit of weak tunnelling. Our results are in good agreement with the finite-temperature phase transition predicted for this state. We also observe an activated insulating behaviour for nu=1, which may be evidence of a correlated bilayer Wigner state.
