Abstract
The effects of flame annealing on the surface structure of polycrystal line gold and platinum electrodes were investigated by scanning tunnel ing microscopy. For gold a pronounced facetting in the (100) direction was observed. The roughness of the platinum sample was significantly reduced by the annealing procedure. On an electrochemically roughened Pt(111) electrode atomic scale resolution was achieved on a surface wi th near-atomic scale roughness.
