Problems solved by technology

This design structure is relatively large and complex, and it is easy to introduce noise and instability
The other is to integrate the sample holder and the scanning base. This structure has better rigidity and stability, but due to the limitation of integrated processing, the space of the scanning probe is narrow and closed, and it is usually difficult to observe the needle tip and sample, unable to monitor the operation process

Abstract

The invention provides a scanning tunneling microscope scanning probe head comprising a sample base which is used for bearing a sample; a scanning pedestal which is used for controlling a scanning probe; and a side plate which is used for rigidly connecting the sample base and the scanning pedestal.

Description

technical field [0001] The invention relates to a scanning probe of a scanning tunneling microscope (STM), in particular to an optically compatible low-temperature scanning probe. Background technique [0002] Since its introduction in 1981, scanning tunneling microscopes have been widely used in many fields such as surface physics science, material science, and life science. The scanning tunneling microscope has extremely high spatial resolution, reaching 0.1nm laterally and 0.01nm vertically. Its appearance enables people to "see" and "manipulate" atoms, thus greatly promoting and promoting the development of nanotechnology. The scanning probe is the core part of the scanning tunneling microscope. It is based on the tunneling effect in quantum mechanics, using a metal needle tip as a probe, making it and the sample surface as two electrodes, when the distance between the sample surface and the needle tip is very close (<1nm), the electron clouds of the two are slightl...
