摘要：
We have measured the low temperature resistance in amorphous SixGe1-x alloy films. Fitting to the theoretical results, we found two kinds of transport regime in the low temperature transport, variable range hopping type (T-1/4) and Coulomb gap type (T-1/2), and can determine the crossover temperature. The crossover temperature clearly depends on the ratio of the alloy composition.
