Abstract

We observed tunneling in a system of interacting electrons confined to a two-dimensional layer. The effects of correlations on the tunneling were studied by varying the electron density from the single-particle limit to the highly correlated Wigner-crystal regime. For low densities the tunneling is well described by a model in which the interactions are represented by an effective potential.
