B. Unal et B. Alkan, THE EFFECT OF DISORDER ON THE ELECTRONIC STATES OF 2-DIMENSIONAL SYSTEMS, Journal of physics. Condensed matter, 7(18), 1995, pp. 3591-3595
Under suitable approximations, it is shown that mobility of electrons
in two-dimensional systems is always zero for a finite value of disord
er, irrespective of the type of scattering potential.
