We present observations of an anisotropic resistance state at Landau-level filling factorin a two-dimensional hole system (2DHS), which occurs for certain values of hole densityand average out-of-plane electric field. The 2DHS is induced by electric-field effect in an undoped GaAs/AlGaAs quantum well, where front and back gates allow independent tuning ofand, and hence the symmetry of the confining potential. ForandV/m, the magnetoresistance alonggreatly exceeds that along, suggesting the formation of a quantum Hall nematic or “stripe” phase. Reversing the sign ofrotates the stripes by. We suggest this behavior may arise from the mixing of the hole Landau levels and a combination of the Rashba and Dresselhaus spin-orbit coupling effects.
