Postprocessing Algorithm for Driving Conventional Scanning Tunneling Microscope at Fast Scan Rates

Figure 1

STM data of a single crystal Cu(111) surface obtained with a fast scan rate (0.1 msec per pixel): (a) topography raw data from forward scan (), scan area  nm², or effective scanning speed  μsec; (b) topography raw data from backward scan (); (c) atomic resolution raw data from forward scan, scan area  nm², or effective scanning speed  nmsec; (d) atomic resolution raw data from backward scan. Bright streaks are indications of possible tip crashes.
