Researchers built a silver atomic switch that forms and breaks single-molecule junctions, enabling stable molecular wiring and advancing scalable, energy-efficient electronics. (Nanowerk News) ...

Electronics keep shrinking, but silicon is starting to run into physical limits. To go smaller, researchers are turning to something far tinier than any transistor on a chip: single molecules that act ...

Using a beam of electrons from a scanning tunneling microscope (STM), researchers at the National Institute of Standards and Technology (Gaithersburg, MD) were able to move a single atom in a small ...

The atomic switch operates by forming and breaking a tiny silver filament inside a thin film of tantalum oxide. When a positive voltage is applied, silver atoms move to create a conductive bridge ...
