Abstract

A fast scanning tunneling microscope (FSTM) is developed using a new method of compensating for the probe tip servo error in constant current mode. The compensation value is derived from the ratio of tunnel current fluctuation to tunnel current (ΔI/I) in a differential tunnel current equation. Dynamic video images of Si(111) adatomic structures taken using the FSTM prove that this method is effective for fast scanning.
