Quantum size effects (QSE) in work functions of free standing and adsorbed thin metal films.
01 January 1984
Work functions vs. film thickness have been calculated self- consistently for free-standing, Al(111), Cr(100), Rh(111) and Au(100) films, and for 1- and 2-layer films of Au(100) adsorbed on Cr(100). The Al, Rh and Au films show work function changes of several tenths of an eV, between 1 and 4 layers, confirming earlier results for free-electron metals and extending them to transition and noble metals.
