We investigated two-dimensional electron-(2DES) and hole systems (2DHS) in the fractional quantum Hall regime for filling factors n ΒΌ 1/3 and n ΒΌ 2/3. Due to a metallic top gate we are able to vary the electron-/hole density of the samples over a wide range. Measuring activated transport on these sy
