Problems solved by technology

These techniques play an important role in the research of various fields of surface science, but any technique has limitations in one way or another in its application, for example, diffraction methods such as low-energy electron diffraction and X-ray diffraction require samples to be periodic. Structure, the resolution of optical microscope and scanning electron microscope is not enough to distinguish surface atoms, high-resolution transmission electron microscope is mainly used for bulk phase and interface research of thin layer samples, field electron microscope and field ion microsc

Abstract

The invention discloses a micronano metal fiber surface topography measuring device, a use method thereof and a movement distance measuring method of a drive in the device. A substrate is arranged on a base through a rail. A chute is arranged in the middle of the base. A template is placed in the chute. A visual window is arranged at the center of the base. One end of a cross beam is connected with the base. One end of a side beam is connected with a support leg, and the drive is arranged on the other end. One end of an electrode is arranged on the side beam. The other end points to the surface of the template through the visual window. The distance from one end, which points to the template, of the electrode to the surface of the template is 0.01 to 100nm. According to the invention, a produced tunnel current effect is used to scan the surface of a measured object, and the three-dimensional shape of the surface of the measured object is acquired through difference in current magnitude.

Description

technical field [0001] The invention relates to a device for measuring the surface topography of micro-nano metal fibers, a method for using the same, and a method for measuring the moving distance of a driver in the device. Background technique [0002] Nano science and technology (Nano-ST) is a new technology that was just born in the late 1980s and is on the rise. Manipulate and arrange atoms and molecules to create new substances. Nanotechnology is one of the important contents of the scientific and technological industrial revolution in the 21st century. It is a highly interdisciplinary and comprehensive subject, involving relevant knowledge of multiple disciplines such as physics, chemistry, biology, materials science and electronics. It not only includes basic disciplines with observation, analysis and research as the main line, but also technical science with nano-engineering and micro-mechanics as the main line. Therefore, nano-science and technology is also a comp...
