Abstract
Useful and simple 3D crossover expressions are derived for the resista nce versus temperature behavior in highly insulating 3D films. At high temperatures, this theory extrapolates to the Mott variable-range hop ping (VRH) law and at low temperatures to the Efros-Shklovskii variabl e-range hopping law. Acceptable fits to experimental data are observed .
