Abstract
Two scanning tunneling microscopes (STMs) operating in air were design ed for imaging samples with dimensions up to 75 mm diam and 25 mm thic kness. Both STMs allow a wide sampling range capability to be obtained by means of xy sample positioning stages spanning 25 mm with 0.1 mum resolution. The automatic tip-sample approach is achieved in the two d evices by moving either the head scanning stage or the sample bolder. These STMs were successfully used to image highly oriented pyrolithic graphite, gratings, and indentations made on hardened steel.
