We don’t usually think of a microscope as an active instrument, but researchers in Canada have used a scanning tunneling microscope to remove or replace single hydrogen atoms from the surface of a ...

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 ...

Scanning Tunneling Microscopy STM: are instruments for imaging surfaces at the atomic level. STM is a non-optical microscope that works by scanning an electrical probe tip over the surface of a sample ...

In the early 1980s, Gerd Binning and Heinrich Rohrer developed the scanning tunneling microscope (STM) at the IBM Zurich Research Laboratory. In 1986, they won a Noble Prize for their breakthrough ...

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 ...

The scanning-tunneling microscope (STM), which is used to study changes in the shape of a single molecule at the atomic scale, impacts the ability of that molecule to make these changes, researchers ...

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 ...

Wouter Jolie and Clifford Murray at the scanning tunneling microscope instrument for low temperatures, with which they investigate the electrons in a box that form the Tomonaga-Luttinger liquid.

The tunable microwave-frequency alternating current scanning tunneling microscope (ACSTM) can document local chemical information and local spectra on insulator surfaces, similar to what the ...

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...

Ohio University physicist Saw Wai Hla and his colleagues were able to scan a single iron atom hidden amid a complex molecule, something that’s never been done with an X-ray before. Extremely powerful ...
