Electrical properties and structure of thin chromium films

The temperature dependence of the electrical resistance of thin chromium films produced by vacuum condensation at 1· 10^–4 mm Hg on mica, optical glass, and rock salt substrates is considered. The electrical resistance of chromium films condensed on substrates heated to temperatures below 450 °C increases irreversibly on subsequent heating and cooling. Chromium films condensed on substrates heated to 500–600 °C, however, retain stable electrical properties on repeatedly heating and cooling.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii Fizika, No. 9, pp. 56–60, September, 1971.
