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 ...

Atoms are 0.1 nm across, and it took 60 years to finally see them clearly
Atoms measure roughly 0.1 nanometers across, a scale so small that scientists spent more than six decades developing ...
This news release is available in German. Jülich, 27 November 2014 - The resolution of scanning tunnelling microscopes can be improved dramatically by attaching small molecules or atoms to their tip.
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 ...
An international research team has succeeded in controlling the chirality of individual molecules through structural isomerization. The team also succeeded in synthesizing highly reactive diradicals ...
Since the early 2010s, ultrafast probing of materials at atomic-level resolution has been enabled by terahertz scanning tunneling microscopes (THz-STM). But these devices can't detect the dissipation ...
Scanning tunneling microscopes capture images of materials with atomic precision and can be used to manipulate individual molecules or atoms. Researchers have been using the instruments for many years ...
