Introduction:

Based on the principle of quantum tunneling effect, the difference in distance between the probe and the sample surface causes changes in tunneling current to obtain atomic surface information, achieving atomic-level imaging of the surface appearance of objects. Real-time dynamic monitoring is carried out through atomic-manipulated electronic state analysis, with high resolution, no damage to the inspected object during detection, good environmental universality, high measurement sensitivity, and clear atomic morphology images obtained.
