摘要：

Non-contact atomic force microscopy (NC-AFM) has been used to image the room-temperature growth of copper and palladium on the (1 x 1) and (root 31 x root 31) R +/- 9 degrees terminations of alpha-Al2O3(0001). Three-dimensional (3D) clusters of palladium are observed on both the (1 x 1) and the (root 31 x root 31) R +/- 9 degrees terminations, with 3D clusters of copper observed on the reconstructed surface. There is evidence of step-edge-dominated growth of palladium on the (root 31 x root 31) R +/- 9 degrees termination. (C) 2000 Elsevier Science B.V. All rights reserved.
