Accelerated mound decay at adjacent kinks on Cu(1 1 1)
Ab initio barriers to concerted downward transport of Cu atoms range from 0.66 to 0.85 eV, when kinks on adjacent Cu(1 1 1) 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." © 2001 Published by Elsevier Science B.V.
