Abstract

The invention provides a large-range searchable scanning probe microscope. The microscope comprises a vertical rod, a positioning block, a linear motor, a fastening nut, a fastening nail, a cross rod,an inertia motor, a bracket and a sample groove; the vertical rod is assembled on the upper end face of the bottom plate; the fastening nut is assembled at the lower side of the annular side surfaceof the vertical rod; the linear motor is assembled on the annular side surface of the vertical rod; the bracket is assembled on the right side of the linear motor; the positioning block is assembled on the upper side of the annular side surface of the vertical rod; the right end surface of the positioning block is connected with the cross rod, the lower end surface of the cross rod is provided with the inertia motor, the upper end surface of the inertia motor is provided with the fastening nail, and the lower end surface of the inertia motor is provided with the sample groove. The design solves the problem of limited scanning range of an existing scanning probe microscope, the structure is reasonable, and the scanning precision of the scanning probe microscope is conveniently improved.

Description

technical field [0001] The invention is a large-scale searchable scanning probe microscope, which belongs to the technical field of scanning probe microscope technology. Background technique [0002] Scanning probe microscopy has a wide range of applications due to its extremely high resolution, observation of real surface topography, and relaxed use environment. The core principle of scanning probe microscopy is to characterize the sample through the tunneling current (scanning tunneling microscope) or atomic force (atomic force microscope) or magnetic interaction (magnetic force microscope) between the probe and the sample. Therefore, the piezoelectric scanning tube is required to drive the probe to perform two-dimensional scanning, so the scanning range of the scanning probe microscope is determined by the scanning head. If you want to scan in a large area, the usual way is to increase the aspect ratio of the scanning tube, or increase the control voltage of the scanning...
