Surface Ionization of Lithium on the 110 and 111 Faces of a Tungsten Single Crystal,

Abstract

Equipment and procedures are described for study of the positive surface ionization of sodium and lithium on uniform surfaces and of sodium on incandescent filaments, in a vacuum of (1-2) X 10 to the -9th power torr. Schottky and Richardson curves and ion current vs. temperature curves are presented. The results are explained by an increase in work function of the surface being studied, with light coatings of sodium and lithium adatoms.
