Abstract

We have studied the near-equilibrium tunnelling between identical two-dimensional electron systems at 0.3 K over a wide range of magnetic field applied normal to the electron layers. The magnetic field suppresses the electron tunnelling. Our results are consistent with the co-existence of two types of tunneling gap. Moreover, at ν < 2 additional features arise in the tunneling spectra, which we interpret in terms of the emission of some as yet unidentified quasiparticle.
