We have realized by cleaved edge overgrowth a two-dimensional electron gas system in a one-dimensional lateral superlattice consisting of 100 periods of 120 Å GaAs/20 Å AlGaAs. These devices exhibit nonlinear I-V, including negative differential resistance, at high electric fields. We demonstrate, by monitoring the changes in the two-dimensional electron density, that the nonlinear I-V is due to high field induced electron trapping.
