Basic physics suggests that electrons are essentially immortal. A fascinating experiment recently failed to overthrow this fundamental assumption. But the effort has produced a revised minimum ...

It may not have won an Oscar, but the tiny electron has finally made its film debut. A new video shows how an electron rides on a light wave after just having been pulled away from an atom. This is ...

AES operates on the principle of the Auger effect, named after the French physicist Pierre Auger. When a material's surface is bombarded with a beam of high-energy electrons or photons, it causes the ...

Carbon nanotube field emitters are at present the brightest available electron sources but must operate at low currents to avoid Coulomb expansion and are therefore not suitable for ultrafast imaging.

Microscopes are of three basic types: optical, electron (or ion), and scanning probe. The modern optical or light microscope was developed in the mid-19th century. Optical microscopes use transparent ...
