Enhancement of the $\nu =5/2$ Fractional Quantum Hall State in a Small In-Plane Magnetic Field

Guangtong Liu, Chi Zhang, D. C. Tsui +5

Using a 50-nm width, ultra-clean GaAs/AlGaAs quantum well, we have studied the Landau level filling factor $\nu =5/2$ fractional quantum Hall effect in a perpendicular magnetic field…
