摘要：

Useful and simple 3D crossover expressions are presented for the resistance versus temperature behaviour in highly insulating 3D films. At high temperatures, this theory extrapolates to the Mott variable-range hopping law, and at low temperatures to the Efros-Shklovskii variable-range hopping law. Good agreement is found between the crossover theory and resistance measurements.
