摘要：

We have used the scanning tunneling microscope in air to investigate the topographic and diffusion properties of the surfaces formed by melting gold and platinum wires into spheres. Nanolithographic parameters, including thresholds for surface modification of the gold and platinum surfaces, have been studied and coefficients for self-diffusion have been determined. The data suggest diffusion rates at room temperature 1-2 orders of magnitude lower on platinum than on gold.
