Abstract | We have measured the magnetoresistance of quantum wires, junctions and rings near Landau filling factor v = 1/2 to search for effects due to composite fermions (CF). We find evidence for semi-classical ballistic effects in the CF which are similar to those seen near zero magnetic field. However, we were not able to observe effects due to the phase coherence of the CF, even where their analogues were apparent in the electron transport. We attribute this to sample inhomogeneity. |
