Atomic force microscopes using tube scanners usually obtain plane data through software correction methods for the curved surfaces generated by the arc motion of the scanner. However, the software correction method cannot completely eliminate the influence of the arc movement of the scanner, and the distortion effect often occurs on the picture.
AFM5500M is equipped with a newly developed horizontal scanner, which can realize accurate testing without being affected by circular arc movement.
Sample ：Amorphous silicon thin film on a silicon substrate

The scanner used in an ordinary atomic force microscope will bend (crosstalk) when it stretches vertically. This is the direct cause of the topography error of the image in the horizontal direction.
The new scanner mounted in the AFM5500M will not bend (crosstalk) in the vertical direction, and can get correct images without distortion in the horizontal direction.
Sample : Textured-structure solar battery(having symmetrical structure due to its crystal orientation.)

◆ 3. Integration
Intimate integration with other detection and analysis methods
Through the SEM-AFM shared coordinate sample stage, the surface morphology, structure, composition, physical properties, etc. of the sample can be quickly observed and analyzed in the same field of view.

The ovrlay images createed by using AZblend Ver.2.1, ASTRON Inc.
The image above is the application data of the shape image (AFM image) and potential image (KFM image) taken by AFM5500M and superimposed on the SEM image respectively.
image.png It can be judged by analyzing the AFM image that the SEM contrast characterizes the thickness of the graphene layer.
image.png The difference in the number of graphene layers results in the contrast of the surface potential (work function).
image.png The contrast of SEM images is different. The reason can be found through SPM's high-precision 3D topography measurement and physical characteristics analysis.
In the future, it is planned to be used in conjunction with other microscopes and analytical instruments.
