Unlike Scanning Electron Microscopy that bounces electrons off the surface of a sample to produce an image, Transmission Electron Microscopes (TEMs) shoot the electrons completely through the sample.
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 ...
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.
