Advances in Imaging and Electron Physics

Electron Emission Physics

Advances in Imaging and Electron Physics merges two long-running serials-Advances in Electronics and Electron Physics and Advances in Optical and Electron Microscopy. This series features extended articles on the physics of electron devices (especially semiconductor devices), particle optics at high and low energies, microlithography, image science and digital image processing, electromagnetic wave propagation, electron microscopy, and the computing methods used in all these domains.This thematic volume is on the topic of "Field-emission Source Mechanisms" and is authored by Kevin Jensen, Naval Research Laboratory, Washington, DC.

Audience
Physicists, electrical engineers and applied mathematicians in all branches of image processing and microscopy as well as electron physics in general
