Abstract

The invention provides a device for moving the sample in the scanning tunneling microscope. The device comprises a shifting fork and a direction mover, the tail end portion of the shifting fork is installed on the direction mover, the front end portion of the shifting fork is provided with a through hole, the front end portion is provided with a notch communicated with the through hole, the direction mover is used for moving the shifting fork in the three-dimensional direction. The invention also provides a method for moving the sample in the scanning tunneling microscope. In the process that the scanning tunneling microscope scans the sample, the probe can penetrate through the notch so that the probe can be located in the range of the through hole, the shifting fork can accurately move the sample to a target position under the condition that the shifting fork does not touch the probe, and therefore the sample can be positioned and fed, namely the specific position of the sample can be scanned; therefore, samples with non-uniform surfaces and different properties can be scanned.

Description
