The probe tip of a scanning probe microscope
Webb4 nov. 2024 · The components of a scanning probe microscope are; a probe with a sharp tip that interacts with the surfaces of specimens, a scanner that helps in controlling the probe, and detectors that detects different signals generated by the probe. It is of the following types: WebbIn detail, we review the main techniques of Scanning Probe Microscopy (SPM), which are Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM), focusing our attention on the latter one. The AFM instrument provides information on the roughness and grain size of thin films.
