摘要：

We present a simple scaling form of Mott's formula of conductivity in case of amorphous materials in an arbitrary dimension d for a density of states which has a soft gap at the Fermi energy. We also indicate the scaling form of the conductivity at a high electric field. Previously known results can be obtained from this generalised form of the conductivity.
