Abstract
We have measured the temperature dependence of the conductivity [Formula presented] of a two-dimensional electron system deep into the localized regime of the quantum Hall plateau transition. Using variable-range hopping theory we extract directly the localization length [Formula presented] from this experiment. We use our results to study the scaling behavior of [Formula presented] as a function of the filling factor distance [Formula presented] to the critical point of the transition. We find for all samples a power-law behavior [Formula presented] in agreement with the theoretically proposed universal exponent [Formula presented].
