Abstract

We report drag measurements on dilute double layer two-dimensional hole systems in the regime of [Formula presented]. We observed a strong enhancement of the drag over the simple Boltzmann calculations of Coulomb interaction, and deviations from the [Formula presented] dependence which cannot be explained by phonon-mediated, plasmon-enhanced, or disorder-related processes. We suggest that this deviation results from interaction effects in the dilute regime.
