Abstract
The first example of a fully self-consistent electronic structure calculation is presented that elucidates the coverage () dependence of the work function and the nature of the adatom-substrate bond for alkali-metal overlayers on a jellium surface. The characteristic dependence of the work function observed widely can be reproduced in a straightforward way, without invoking a clustering among adatoms and/or a dependence of the adatom-substrate distance.
