Scanning Probe Microscope (SPM)
Scanning probe microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. SPM was founded with the invention of the scanning tunneling microscope in 1981.
Applications
- Atomic-scale imaging of solid surfaces
- Research on catalytic agents
