Maximum of the mobility of two-dimensional electrons upon scattering by a correlated distribution of impurity ions

Influence of correlations in a flat distribution of impurity ions on the mobility of two-dimensional electrons at low temperatures

“…Under these condi tions, the temperature dependence of the mobility of degenerate two dimensional electrons is completely determined by the structure factor: (10) Here, 〈S(q)〉 T is the thermodynamic average of the structure factor according to the calculation from rela tionship (6).…”

“…In our previous studies [5,6], we considered the spatial correlations of impurity ions in rather wide doped layers, for which the width of the layer W d is larger than the correlation length r c (r c < W d ). The cal culations were performed within the framework of the standard model of hard spheres distributed in the vol ume.…”
