Abstract

We have investigated tunnelling between disordered two-dimensional electron systems in a magnetic field parallel to the current. At liquid-helium temperatures, the high magnetic field creates a gap in the tunnelling density of states that depends linearly on magnetic field. The temperature dependence of the magnetic field variation of the equilibrium tunnelling conductance reveals features which could be interpreted as a manifestation of the insulator-quantum Hall-insulator transition.
