Abstract

The structure and the composition of the Ca-segregated MgO(001) surface were investigated by using time-of-flight impact-collision ion scattering spectroscopy and Rutherford backscattering spectroscopy. MgO including 210 ppm Ca impurities in bulk was heated at a temperature of 1400°C for 5 h in the oxygen atmosphere. It is found that Ca ions, being segregated with an amount of (2.14±0.04) × 10¹⁴ ions cm^-2, exist only in the outermost layer, and no Ca enrichment occurs in the deeper layers.
