We compare directly the metallic behavior of high-quality, two-dimensional hole systems (2DHSs) in two GaAs device structures-one dominated by short-range disorder and the other by long-range disorder. We find that the type of disorder strongly affects the metallic behavior of the 2DHSs. In particular, we find that metallic behavior is enhanced in 2D systems with a high proportion of large-angle scattering events.
