✦ Synopsis

We present magnetoconductivity measurements of two-dimensional non-degenerate electrons on liquid helium at 1:22 K. We measured the magnetoconductivity from an extremely low density where e-e interactions are negligible to densities where Coulomb interactions dominate the width of the density of states peaks. We observe a crossover from Drude theory to SCBA as a function of both magnetic ÿeld and electron density at ÿnite classical ÿelds.
