Abstract / Description:We have investigated equilibrium tunnelling between disordered
two-dimensional electron systems at temperatures below 0.3 K
over a wide range of magnetic field. B. applied perpendicular
to the electron layers. In zero field, we observe a narrow
conductance peak of about 1 mV width at zero bias. As B is
increased, this is transformed into a narrow linear gap in the
tunnel spectrum. The existence of the linear gap is discussed
in terms of many-electron interaction effects. (C) 2002
