Abstract

An experimental study of commensurability oscillations in anisotropic antidot lattice is performed. A fundamental peak of the resistivity tensor is determined by a peak of the conductivity tensor perpendicular to the current flow direction in the case of smaller diagonal component of conductivity than the off-diagonal one. Moreover, by using the model of electron diffusion along the antidot array, the peak of conductivity is explained. At the peak of conductivity, the electron can diffuse along the antidot array by skipping over the antidots, and the conductivity is enhanced.
