Photoelectron emission from lithiated diamond
MetadataShow full item record
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.

Ab Initio Calculations of the Main Crystal Surfaces of Forsterite (Mg2SiO4): A Preliminary Study to Understand the Nature of Geochemical Processes at the Olivine InterfaceBruno, M.; Massaro, F.; Prencipe, M.; Demichelis, Raffaella; De La Pierre, M.; Nestola, F. (2014)We present an accurate ab initio study of the structure and surface energy at 0 K of the (010), (101), (111), (001), (110), (120), and (021) faces of forsterite (Mg2SiO4) using the hybrid Hartree–Fock/density functional ...
O’Donnell, Kane; Martin, T.; Fox, N.; Cherns, D. (2010)We have performed ab initio calculations to investigate the adsorption of Li onto the clean and oxygenated diamond C(100) surface. Despite a large amount of interest in alkali-metal absorption on clean and oxidized ...
O'Donnell, Kane; Edmonds, M.; Tadich, A.; Thomsen, L.; Stacey, A.; Schenk, A.; Pakes, C.; Ley, L. (2015)We report large negative electron affinity (NEA) on diamond (100) using magnesium adsorption on a previously oxygen-terminated surface. The measured NEA is up to (-2.01±0.05) eV, the largest reported negative electron ...
