  "abstract": "We have measured the temperature dependence of the conductivity $\\sigma_{xx}$ of a two-dimensional electron system deep into the localized regime of the quantum Hall plateau transition. Using variable-range hopping theory we are able to extract directly the localization length $\\xi$ from this experiment. We use our results to study the scaling behavior of $\\xi$ as a function of the filling factor distance $|\\delta \\nu|$ to the critical point of the transition. We find for all samples a power-law behavior $\\xi\\propto|\\delta\\nu|^{-\\gamma}$ with a universal scaling exponent $\\gamma = 2.3$ as proposed theoretically.",
