Query: Short-range disorder effects on electronic transport in 2D semiconductor
  structures   We study theoretically the relative importance of short-range disorder in
determining the low-temperature 2D mobility in GaAs-based structures with
respect to Coulomb disorder which is known to be the dominant disorder in
semiconductor systems. We give results for unscreened and screened short-range
disorder effects on 2D mobility in quantum wells and heterostructures,
comparing with the results for Coulomb disorder and finding that the asymptotic
high-density mobility is always limited by short-range disorder which, in
general, becomes effectively stronger with increasing `carrier density' in
contrast to Coulomb disorder. We also predict an intriguing re-entrant
metal-insulator transition at very high carrier densities in Si-MOSFETs driven
by the short-range disorder associated with surface roughness scattering.
