Webwww.physics.gatech.edu WebMar 15, 2006 · The significant reduction of σ 2D at Au coverage of 1.4 ML is probably due to the presence of such a critical size. The present analysis clarifies the fact that the critical size governs the growth mode of Au clusters on NiO(0 0 1) rather than critical Au coverage. If the size of 2D-islands exceeds the critical one, growth of 3D-islands ... rapid sneeze
