Title
Getting Close to the Single Atom
Abstract
Atomic force microscopy (AFM) relies on forces of various origin and range and used to be inferior in resolution to scanning tunneling microscopy (STM). Today, AFM exceeds STM in resolution, using Pauli repulsion forces that became accessible with the invention of the qPlus sensor, a device that used the heart of Swatch watches. Today, we can measure the forces that act in atomic manipulation, sub-pN exchange interactions, image clusters and molecules with atomic resolution and resolve structures within single atoms.
