Fig. 3.28 Influence of the distance on the work function of N-adsorbed W(100) [30]. The left
figures show top (a) and side (b) views of the atomic arrangement, the upper right figure (right (a))
shows the charge distribution as a function of vertical distance, and the bottom right figure (right
(b)) shows the change in the work function as a function of distance
