Abstract:
1. A probe position control system for performing a control of a relative position of a probe and a sample while measuring an interaction between an atom on a sample surface and a tip of the probe to obtain an atomic-level image of the sample surface or perform a certain manipulation on the atom on the sample surface, comprising: a) a measuring device for measuring the aforementioned interaction in a direction perpendicular to the sample surface; b) an oscillator for relatively oscillating the probe and the sample in two directions parallel to the sample surface at frequencies of f c) a tracker for measuring the aforementioned interaction, before the control of the relative position of the probe and the sample, while relatively moving the probe and the sample, for detecting a point where the frequencies f d) a speed detector for determining a speed of the aforementioned relative movement created by the tracker; and e) a corrector for correcting the control of the relative position of the probe and the sample using the detected speed.
