Anisotropic Disorder in High Mobility 2D Heterostructures and its Correlation to Electron Transport

R. L. Willett, J. W. P. Hsu, D. Natelson +2

Surface morphology of high mobility heterostructures is examined and correlated with d.c. transport. {\it All} samples examined show evidence of lines in the [1$\bar{1}$0] directio…
