Annotation
On the basis of scale theory of localization, it is shown that the activational temperature dependence of the conductivity of two-dimensional systems, usually interpreted by means of the concept of a mobility edge, may be due to the finite value of the characteristic length - the dimension of the system or the diffusional length including the free-path time with respect to inelastic collisions.
