Diffusion conductivity and weak localization in two-dimensional structures with electrostatically induced random antidots array
Abstract
Results of experimental study of the weak localization phenomenon in 2D system with artificial inhomogeneity of potential relief are presented. It is shown that the shape of the magnetoconductivity curve is determined by the statistics of closed paths. The area distribution function of closed paths has been obtained using the Fourier transformation of the magnetoconductivity curves taken at different temperatures. The experimental results are found in a qualitative agreement with the results of computer simulation.
