Impact Of Short-Range Scattering On The Metallic Transport Of Strongly Correlated Two-Dimensional Holes In Gaas Quantum Wells, Nicholas J. Goble, J. D. Watson, Michael J. Manfra, Xuan P.A. Gao
Birck and NCN Publications
Understanding the nonmonotonic behavior in the temperature dependent resistance R(T) of strongly correlated two-dimensional (2D) carriers in clean semiconductors has been a central issue in the studies of 2D metallic states and metal-insulator transitions. We have studied the transport of high mobility 2D holes in 20-nm-wide GaAs quantum wells with varying short-range disorder strength by changing the Al fraction x in the AlxGa1-xAs barrier. Via varying the short-range interface roughness and alloy scattering, it is observed that increasing x suppresses both the strength and characteristic temperature scale of the 2D metallicity, pointing to the distinct role of short-range vs long-range …
