Abstract

Novel process for forming a gold crystal film with high (111) orientation on a substrate has been established using a supersaturated solution of [AuI₄]¯. The gold crystal film has a grain size of approximately 200 μm and an atomically flat surface, which provides sufficient quality for the substrate of SPM observation. High resolution and accuracy AFM images for a plasmid DNA thus have been obtained using the gold crystal film. [DOI: 10.1380/ejssnt.2005.524]
