Abstract

The invention relates to a circular-tube-shaped externally-insulated narrow-size lens body of a scanning probe microscope. The circular-tube-shaped externally-insulated narrow-size lens body comprisesa circular-tube-shaped insulated frame, a circular-tube-shaped piezoelectric motor, a circular-tube-shaped scanning unit, a probe and a sample table, the circular-tube-shaped piezoelectric motor is fixed on one internal end of the circular-tube-shaped insulated frame coaxially, a stepping direction of a free end of the circular-tube-shaped piezoelectric motor coincides with an axial direction ofthe circular-tube-shaped insulated frame, the sample table is arranged at the other end of the circular-tube-shaped insulated frame, the circular-tube-shaped scanning unit comprises a sliding block, asliding block spring piece, a circular-tube-shaped four-quadrant XYZ piezoelectric scanning tube and the probe, the sliding block spring piece elastically presses a sliding rod onto the circular-tube-shaped insulated frame, an axial direction of the sliding block coincides with that of the circular-tube-shaped insulated frame, one end of the sliding block points to the free end of the circular-tube-shaped piezoelectric motor, and the other end of the sliding block is coaxially provided with the circular-tube-shaped four-quadrant XYZ piezoelectric scanning tube. The scanning probe microscope lens body is narrow in size, free from conducting loops on a cross section, applicable to extreme physical conditions including extremely-low-temperature conditions, high-intensity magnetic fields andthe like, and particularly applicable to quick-change magnetic fields.

Description

technical field [0001] The invention discloses a circular tube-shaped external insulating narrow-sized scanning probe microscope mirror body, which belongs to the technical field of scanning probe microscopes, and in particular relates to scanning tunneling microscopes. Background technique [0002] Scanning probe microscopes mainly include scanning tunneling microscopes, atomic force microscopes, magnetic force microscopes, etc., which can provide microscopic material surface information and are widely used in the field of surface science research. In particular, scanning tunneling microscopy can obtain in situ atomic resolution structure and energy band information on the surface of materials, which is an essential research method for condensed matter physics. Especially in combination with strong magnetic field and extremely low temperature conditions, strange and important physical properties can be directly observed, such as the charge order of high-temperature supercon...
