At its core, SPM operates on the principle of measuring interactions between a sharp probe and the surface of a material. As the probe scans across the surface, it detects variations in physical ...

Overview of the main types of Scannig Probe Microscope types: Scanning tunneling microscope (STM) – using the tunneling current I between the outermost atom of a conducting probe within an atomic ...

How it works: illustration of the quantum twisting microscope in action. Electrons tunnel from the probe (inverted pyramid at the top) to the sample (bottom) in several places at once (green vertical ...
