Abstract
A study of the Schottky barrier for lead (Pb) films grown on Si surfaces that were terminated by several various metals was discussed. It was found that an angle resolved photoemission was employed to determine the barrier height in each case. The barrier height was determined from the atomic layer resolved energy levels and the line widths. The results show that a calculation based on the known interface chemistry and the electronegativity yields predicted barrier heights in good agreement that were useful for barrier engineering.
