Area of Science:

• Surface science and material science
• Nanotechnology
• Microscopy

Background:

• Scanning probe microscopy (SPM), including atomic force microscopy (AFM), excels at 2D surface imaging and nanolithography.
• Current SPM techniques are limited in their ability to construct and visualize complex 3D structures.

Purpose of the Study:

• To develop a new algorithm for constructing and displaying layer-by-layer 3D structures from SPM images.
• To enable high-resolution 3D imaging and visualization using SPM data.
• To advance SPM capabilities for 3D applications.

Main Methods:

• A novel algorithm was developed to process SPM images acquired during layer-by-layer deposition and removal.
• The algorithm aligns images, removes redundant features, and reconstructs 3D structures.
• A "see-through" display strategy was implemented for visualizing individual layers within the 3D structure.

Main Results:

• The algorithm successfully constructs 3D structures from SPM images with high spatial accuracy.
• The "see-through" display allows clear visualization of each layer.
• The algorithm demonstrated versatility, allowing user-defined parameters for reconstruction and display.

Conclusions:

• This work presents the first method to enable SPM technology for 3D imaging construction and display.
• The provided algorithm facilitates the use of this approach in various SPM software.
• These advancements support applications in 3D nanoprinting, additive/subtractive manufacturing, and imaging.
