Phys. Rev. Lett. 93, 226101 (2004) [4 pages]Reduction of Cu2O Islands Grown on a Cu(100) Surface through Vacuum AnnealingReceived 29 April 2004; published 22 November 2004 The reduction of Cu2O islands grown on Cu(100) surfaces through vacuum annealing was visualized by an in situ ultrahigh vacuum transmission electron microscope. The shrinkage of the island followed a linear decay behavior. The complete reduction of the oxide islands leads to the formation of nanoindentations on the Cu surfaces. A simple phenomenological kinetic model based on the dissociation along the island perimeter suitably describes the reduction behavior of the surface oxide islands. © 2004 The American Physical Society URL:
