A research team led by Professor Hyung-Joon Shin from the Department of Materials Science and Engineering at UNIST has ...
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 (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 ...
IBM’s Scanning Tunneling Microscope, or STM for short, uses an atomically sharp needle that passes over the surface of an (electrically conductive) object – the distance between the tip and ...
The tip's position is meticulously adjusted using piezoelectric controls to maintain a constant tunneling current, allowing the device to image surfaces with atomic precision. Scanning Tunneling ...
Abstract Proton tunneling through a hydrogen bond is a significant quantum phenomenon in proton-mediated processes. Hydrogen ...

50 Years Later, Scientists Just Found a Quantum “Butterfly” Hiding in GrapheneIn a discovery that brings a legendary quantum theory to life, physicists at Princeton University have directly observed ...
Left: Overview scanning tunneling micrograph of a sample containing triangulene quantum spin chains, where chains containing between two to seven triangulene units are highlighted. Right ...
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 ...
