Show affiliationsThe interactions of V with Cr2O3(0001) films and Cr with V2O3(0001) films at room temperature are studied using x-ray photoelectron spectroscopy and low-energy-electron diffraction. The results show that the deposited V is oxidized and the Cr2O3(0001) surface is reduced at the initial coverage due to the interaction of V with the Cr2O3 substrate; V becomes metallic at V coverage greater than 5 monolayer equivalent. Full oxidization of the deposited vanadium cannot be achieved by O2 exposure at room temperature for 20 min. However, V2O3(0001) films have been observed after heating the sample to 600-700 K in oxygen ambient at 1×10-7 mbar. Similar results have been obtained for the Cr/V2O3(0001)/Re(0001) system.
