SiOx as a model medium with large-scale potential fluctuations
Gritsenko V. A., Kostikov Yu. P., Romanov N. A.
A model of large-scale potential fluctuations resulting from a local composition inhomogeneity is constructed from data on SiO^ found by photoelectron spectroscopy. Electron-transport experiments confirm the predictions of the three-dimensional theory of percolation in a large-scale potential relief.
