Abstract
Roughening and islanding of monolayer Ce coverage on vicinal Si(001) s urface has been studied using scanning tunneling microscope (STM). For a 3.9 degrees miscut surface, planar buckled-dimer surface is a metas table state limited by a barrier, which can be overcome by a 680 degre es C annealing. After the annealing, the metastable flat surface has b een changed to a rough surface of small hills because of step-bunching , and on top of each hill, a 3 dimensional (3D) nanoscale island was o bserved. The mechanism of this roughening and islanding process have b een discussed. (C) 1998 Elsevier Science B.V.
