摘要：

Substantial effects of combinations of H and C impurities on wetting of metals on alpha-Al2O3(0001) have been found from first principles. An ab initio surface phase diagram for H and C on the alumina surface reveals six distinct surface phases, consistent with the observed stability of H and C on Al2O3 surfaces. These different surface phases exhibit a variety of adhesion strengths with Cu and Co, and correspondingly different wetting behaviors. These results are consistent with the variety of wetting characteristics observed experimentally.
