Thin films of chromium are deposited on polycrystalline polished Al2O3 substrates at room temperature using vacuum arc (cathodic) sputtering technique. The gas atmospheres of Ar, N2, Ar+O2(30%), CO2, and normal atmosphere at a pressure of 9· 10−2 Pa were used during the film deposition. The structural and microstructural investigations were made by X-ray diffraction and transmission elctron microscopic techniques. The electrical resistivity was measured using 4–point technique in the temperature range of 20 and 500 K and the temperature coefficient of resistivity (TCR=(1/ρ )· (dρ /dT)) was determined. A relationship among the electrical, structural and microstructural properties of the films is discussed.
The work of A.Ya. Vovk was partially supported by INTAS program.
