摘要：
We measure the electrical conductivity in the dissipative regime between adjacent integral quantum Hall plateaus. Variable-range-hopping transport is found, in accordance with a recent theory. The characteristic temperature for hopping conduction follows a power-law dependence on filling factor. Conductivity-peak broadening with increasing current is studied and a power-law dependence is observed.
