Abstract
Studies of a range of alkali antimonides and high-sensitivity S20 and S25 type multialkali photocathodes have led to an improved understanding of this type of photoemitter. In particular the role of Cs is clarified and the low work-function is believed to derive from a Cs-Sb dipole layer.Keywords
