From: High-mobility capacitively-induced two-dimensional electrons in a lateral superlattice potential
(a) Electron mobility 
as a function of electron density 
for the superlattice sample at T = 0.3 K. (b) The ratio of mobilities of the superlattice sample and an un-patterned sample (
) versus density 
. (c) The mean free path 
for the superlattice sample calculated from the mobility curve. The empty circles mark the onset of commensurate oscillations.
