| dc.description | We present the first experimental study of the carrier density dependence of the composite fermion conductivity σ<sub>xx</sub><sup>CF</sup> at Landau level filling factors ν = 1/2 and 3/2 in high-quality front-gated GaAs/Al<sub>0.33</sub>Ga<sub>0.67</sub>As heterostructures. Extracting α from the power law shows that . The measured is placed between the predicted value 3/4 in the strong random magnetic field regime, and 3/2 in the weak random magnetic field regime. Comparisons between our results and theory are discussed. |
