Abstract

Tilt induced anisotropic transport is observed in a series of three wide GaAs quantum wells. In the absence of tilt the transport is isotropic and well developed quantum Hall states are observed. For large values of tilt (θ>60°) the quantum Hall states at ν=5 and 7 are replaced by strongly anisotropic states in the two widest wells, occurring at slightly lower values of θ for the widest well. A similar transition is also seen at ν=9 in the widest quantum well. This transition is not observed in the narrowest quantum well up to the largest tilt angle measured.
