摘要：

We report on the adsorption and reaction of magnesium on Cr2O3(0001)/Cr(110) thin films. X-ray photoelectron spectroscopy (XPS) and X-ray induced Auger-spectroscopy (XAES) reveal the formation of magnesium oxide and chromium metal. The validity of bulk thermodynamic calculations for the estimation of chemical reactivity on surfaces is critically revisited.
