Abstract
A review is given on the hopping conductivity in disordered solids. Variable range hopping between localized electronic states near the Fermi level in amorphous tetrahedrally coordinated semiconductors is discussed in particular. The percolation theory for this type of transport is presented and used to discuss the various transport experiments. These include the dependence of the dc conductivity on heat treatment, applied field, thickness of the samples, and on ion bombardment. It is shown that these effects can be explained satisfactorily by ad hoc models for the density of localized states, although a real understanding of the nature and distribution of these states is still lacking.

This is true for the dc current only. At finite frequencies chains of finite length will contribute to the conductance as well as the change in occupation probability of the sites caused by the external field.
