We prepared highly rectifying and thermally stable Schottky contacts by deposition of colloidal graphite on various semiconductor materials. In collaboration with the Chernivtsi National University we have shown that current-voltage characteristics of the graphite-based Schottky diodes and their temperature variations can be described by the theory of the generation-recombination in the space charge region.
