The dependence of the Composite Fermion effective mass on carrier density and Zeeman energy
Measurements of the temperature-dependent resistivity of high-mobility GaAs/GaAlAs heterojunctions are used to measure the effective mass of Composite Fermions (CF). The CF effective mass is found to increase approximately linearly with the effective field B∗ up to effective fields of 14 T. Data from all fractions around ν = 1/2 are unified by the single parameter B∗ for samples studied over a ...
متن کاملPulsed-magnetic-field measurements of the composite-fermion effective mass.
Magnetotransport measurements of Composite Fermions (CF) are reported in 50 T pulsed magnetic fields. The CF effective mass is found to increase approximately linearly with the effective field B * , in agreement with our earlier work at lower fields. For a B * of 14 T it reaches 1.6m e , over 20 times the band edge electron mass. Data from all fractions are unified by the single parameter B * f...
