Chirality—the property of an object that is distinct from its mirror image—has long captivated scientists across biology, ...

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!

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 ...

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 ...

Nanosurf took it a step further in 1997, bringing single atoms into the classroom! The NaioSTM is a scanning tunneling microscope that combines the scan head and controller into a single instrument ...

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 ...

The paper provides a detailed explanation of how the profile of the light collected in a scanning tunneling microscope (STM) experiments changes when the tip is placed on an atomic step.

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 RHK R9 STM is capable of atomic resolution imaging and tunneling spectroscopy measurements on conductive and semiconductor surfaces under ultra-high vacuum, both at room temperature (~295K) and at ...

They employed advanced analysis techniques, specifically Scanning Tunneling Microscopy (STM), to manipulate the molecules individually and study the resulting configurations. The water molecules ...
