Popis:	Thin films of chromium oxides were deposited on Si substrates by KrF laser ablation of a chromium target in O(2) atmosphere (0.05-5.0 Pa). Films exhibit semiconducting properties with band gap increasing (0.32-0.71 eV) with increasing pressure from 0.05 to 1.0 Pa. The largest values of the thermoelectromotive force coefficient S (similar to 3.5-4.5 mV/K) were measured in the temperature range 270-290 K for the film deposited at 1.0 Pa. The S coefficient decreases in the same temperature range for the film deposited at lower oxygen pressures.
