Interlayer Tunneling in Counterflow Experiments on the Excitonic Condensate in Quantum Hall Bilayers
- Journal Article
The effect of tunneling on the transport properties of quantum Hall double layers in the regime of the excitonic condensate at a total filling factor one is studied in counterflow experiments. If the tunnel current I is smaller than a critical IC, tunneling is large and is effectively shorting the two layers. For I>IC tunneling becomes negligible. Surprisingly, the transition between the two tunneling regimes has only a minor impact on the features of the filling-factor one state as observed in magnetotransport, but at currents exceeding IC the resistance along the layers increases rapidly. © 2010 The American Physical Society.
