Abstract
This paper reviews electron emission from negative electronaffinity (NEA) diamond and gives account of the recentdevelopments in alternatives to hydrogen-termination forproducing NEA diamond surfaces, particularly using lithiumon oxygen-terminated diamond. We discuss the backgroundand motivation for using alkali metals and present bothexperimental and computational results that cover structure,electronic properties, photoemission, and total photoyield.Secondary yield enhancement of over 200 is demonstratedover a reference surface with positive electron affinity.
