Technical Field

The invention discloses a large-range searchable scanning probe microscope, and belongs to the technical field of scanning probe microscopes.

Background

The scanning probe microscope has wide application fields due to extremely high resolution, observation of real surface morphology and loose use environment. The core principle of the scanning probe microscope is to characterize a sample through tunneling current (scanning tunneling microscope) or atomic force action (atomic force microscope) or magnetic interaction (magnetic force microscope) between a probe and the sample. Therefore, the piezoelectric scanning tube is required to drive the probe to perform two-dimensional scanning, so that the scanning range of the scanning probe microscope is determined by the scanning head. If a large scan is desired, it is now common to increase the aspect ratio of the scan tube, or to increase the control voltage of the scan tube, or to move the sample using a two-dimensional motion stage. As published (bulletin) No.: CN102384986A and publication (bulletin) No.: CN106053886B relates to a large-scale scanning probe microscope, but its principle of large-scale implementation is realized by a manual stage.

The invention solves the problem that the scanning range of the existing scanning probe microscope is limited. The inertial motor is controlled to swing through the other piezoelectric tube, so that the sample (or the probe) is driven to move in any direction on a two-dimensional plane, and the full-sample range can be scanned. Will contribute to the wide-range searchable scanning of scanning probe microscopes, there is an urgent need for a wide-range searchable scanning probe microscope to solve the above-mentioned problems.
