摘要
A field-emission electron gun including an electron emission tip, an extractor anode, and a mechanism creating an electric-potential difference between the emission tip and the extractor anode. The emission tip includes a metal tip and an end cone produced by chemical vapor deposition on a nanofilament, the cone being aligned and welded onto the metal tip. The electron gun can be used for a transmission electron microscope.
