In a discovery that brings a legendary quantum theory to life, physicists at Princeton University have directly observed ...

Scanning tunneling microscopy (STM) is an experimental technique based on the principles of quantum tunneling of electrons between two electrodes separated by a potential barrier, typically used for ...

Scanning Tunneling Microscopy is a subset of Scanning Probe Microscopy (SPM), a group of techniques that image and manipulate surfaces at the nanometer to atomic scales. SPM techniques share the ...

Abstract Proton tunneling through a hydrogen bond is a significant quantum phenomenon in proton-mediated processes. Hydrogen ...

The reason for the high-speed micro is the need to control the scanning signals based on the measured tunnelling current to form a control loop. We didn’t dig into precisely how that works!

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 ...

To explore these tiny realms, scientists turn to a scanning tunneling microscope, which operates much like a record player.

These techniques measure variations in physical properties such as force, capacitance, tunneling current ... of SPM techniques with other microscopy and spectroscopy methods, the development of ...

This is an illustration of a buckydiamondoid molecule under a scanning tunneling microscope (STM). The sharp metallic tip of the STM ends in a single atom; as it scans over a sample, electrons ...
