Resistance Fluctuations in Composite Fermion State near Landau Level Filling Factor $\nu =1/2$ in A Square Quantum Well

Jian Zhang, R. R. Du, J. A. Simmons +1

We have studied the magnetotransport near Landau level filling factor $\nu =1/2$ in a GaAs-Al0.3Ga0.7As square quantum well (width 35 nm) in magnetic field up to 42 T and in a temper…
