摘要：

Ab initio barriers to concerted downward transport of Cu atoms range from 0.66 to 0.85 eV, when kinks on adjacent Cu(111) terraces are close. The lowest of these permits mound decay to proceed much faster, at 300-340 K, than when terraces are farther apart, and decay is limited by formation of Cu adatoms and their passage over an island-edge "Schwoebel barrier."
