Abstract

A universal scaling function, describing the crossover between the Mott and the Efros-Shklovskii hopping regimes, is derived using the percolation picture of transport in strongly localized systems. This function agrees very well with experimental data. Quantitative comparison with experiment allows for the possible determination of the role played by quasiparticles in transport.
