Electronics keep shrinking, but silicon is starting to run into physical limits. To go smaller, researchers are turning to ...

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) ...

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 ...
