(from left) Au (111) in 0.1M HClO4, iodine-modified Au (111) in HClO4, rotated-hexagonal superstructure of iodine-modified Au (111) in 0.1M HClO4, and the porphyrin TMPyP on iodine-modified Au (111) in 0.1 M HClO4.    (Left) Time-lapse images of a 200 nm2 region of the Au (111) surface acquired in electrolyte at 2.5 minute intervals after 30 minutes of equilibration demonstrating relatively linear drift of £ 2 nm/min. (Right) Long term chart of engaged Z-position after 30 minutes of equilibration in the electrochemical STM application.
