The Low Energy Auger Electron Spectroscopy Lines as an Index of the Ba Overlayer Order on the Ni(110) Surface
Figure 3
The structural adsorption models of the (a) disordered, (b) Ba-c(), and (c) Ba-(), on the Ni(110) surface. The circles in the models represent the atoms of Ba (dark circles) and Ni (empty circles). The sizes of the circles are proportional to the metallic diameters of Ba and Ni atoms. The unit cells are noticed with the dashed lines.
