Anisotropic Transport of Two-Dimensional Holes in High Landau Levels
arXiv:cond-mat/9903405 · doi:10.1016/S1386-9477(99)00056-9
Abstract
Magnetoresistance data taken along $[\bar{2}33]$ and $[01\bar{1}]$ directions in a GaAs/AlGaAs two-dimensional hole sample with van der Pauw geometry exhibit significant anisotropy at half-integer filling factors. The anisotropy appears to depend on both the density and symmetry of the hole charge distribution.
