dc.descriptionWe have measured the tunneling between two two-dimensional electron gases (2DEGs) in weak magnetic fields, when the carrier densities of the two electron layers are matched. At zero magnetic field, B=0, the lineshape of the equilibrium tunneling resonance is best fit by a Lorentzian, with a linewidth which is determined by the roughness of the tunnel barrier. For $B\not=0$ with filling factors $ν\gg 1$, there is a suppression of the resonant tunneling conductance about zero bias, $V_{\text{sd}}=0$. This low field signature of the high field Coulomb gap shows the same linear $B$ dependence as previously measured for $ν<1$.
