Problems solved by technology

The piezoelectric ceramic scanners currently used in the market mainly include tripod type, single-tube type and multi-tube type, etc. The tripod type scanner is complicated to manufacture and the cost is high, while the multi-tube piezoelectric ceramic scanner has a relatively large scanning range. Large, but at the cost of sacrificing scanning accuracy. At the same time, multi-tube splicing requires extremely high concentricity of the tubes. The current technology is not mature enough, and the production success rate is low.

Abstract

The invention relates to the technical field of electron microscopes and particularly relates to a high-precision piezoceramic scanner. The high-precision piezoceramic scanner comprises a support, a piezoelectric tube body, a shell, a cover, a first wire, a second wire, a connector and a ceramic tube, wherein the support is fixed inside one end of the shell. according to the high-precision piezoceramic scanner provided by the invention, while the scanning precision is ensured, the making process is simple, the success rate is high, the cost is low, the high-precision piezoceramic scanner can be applied to a scanning tunneling microscope and a scanning probe microscope, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the technical field of electron microscopy, in particular to a high-precision piezoelectric ceramic scanner. Background technique [0002] Piezoelectric ceramic scanner is one of the core components of scanning tunneling microscope (STM) and scanning probe microscope (SPM). , and it is also the direct source of measurement data, so it has a great influence on the measurement accuracy and measurement range of STM and SPM. The piezoelectric ceramic scanners currently used in the market mainly include tripod type, single-tube type and multi-tube type, etc. The tripod type scanner is complicated to manufacture and the cost is high, while the multi-tube piezoelectric ceramic scanner has a relatively large scanning range. Large, but at the expense of scanning accuracy. At the same time, multi-tube splicing requires extremely high concentricity of the tubes. The current technology is not mature enough, and the production success rate...
