摘要：

A simple and reproducible method for the preparation of gold films on mica with large (typically 0.8-1.0 mum) atomically flat (111) terraces is described. The procedure involves thin gold film evaporation onto freshly cleaved mica substrates, followed by 1 min annealing at 650degreesC under nitrogen. The annealed gold surfaces are compared to those of freshly evaporated gold films on mica using cyclic voltammetry and atomic force microscopy. Our results favorably compare to other published annealing techniques, with minimal equipment and time necessary to reproducibly obtain atomically flat gold terraces. (C) 2004 Elsevier B.V.
