摘要：

We study magneto-transport properties of a 70 nm-period lateral surface superlattice (LSSL) utilizing self-organized GaAs multiatomic steps formed on GaAs (001) vicinal substrates. We measure four-terminal magnetoresistance (MR) and Hall resistance (HR) for current flow perpendicular and parallel to the multiatomic steps. Unique MR characteristics such as positive MR, amplitude modulation, phase inversion are clearly observed in high magnetic fields in spite of less anisotropy in HR. The results are clearly explained by the predicted theories based on the spectra of Landau subbands.
