This article was updated on the 19th August 2019. A scanning tunneling microscope (STM) is a non-optical microscope that works by scanning an electrical probe tip over the surface of a sample at a ...

For maximum resolution in a scanning tunneling microscope (STM), an extremely sharp metallic tip is required, which serves as the point through which the STM “scans” a sample. A blunt tip reduces STM ...

The Scanning Tunneling Microscopy (STM) was the first technique; in fact, it was invented in 1981 by Gerd Binnig and Heinrich Rohrer at IBM Zurich and after five years they won Nobel Prize in physics.

In the last few years, a magnetic characterisation technique involving scanning tunnelling microscopy (STM) measurements with a magnetic nickelocene molecule has been developed. This technique ...

More than 30 years after achieving atomic resolution with scanning probe microscopes, scientists remain endlessly fascinated with the ability to “see” and study individual atoms and molecules. For ...

Using theoretical calculations of forces and currents, researchers in Spain and the Czech Republic have shown that the bright spots seen in scanning-tunnelling and atomic-force microscope images may ...

Back gate voltage determines whether a waveguide or electron trap is produced. Using the electric field of a scanning tunnelling microscope (STM), scientists in the US, Europe and Japan have created ...
