“…8 Typical materials used for thermionic emission include thoriated tungsten, 9 caesium oxide terminated molybdenum, 10 and LaB 6 . 11 While more recently, materials such as carbon nanotubes, 12,13 diamond, 14 and GaN 6 have sparked a renewed interest in the field. In the case of diamond and GaN, they rely on specific surface terminations like hydrogen and caesium, respectively, in order to lower the work function of the surface, inducing a negative electron affinity 15,16 that makes thermionic emission possible.…”
