Results for attractive interaction

So far we have treated repulsive interactions. Now we turn to the investigation of systems with attractive interactions E 0). In Fig. 9.22 the particle densities and the production rate are shown as a function of Vco for D = 0 and 0.05. The energetic parameters are Jaa = E AB = 0 

In Fig. 9.23 the effective desorption rate is shown as a function of co for D = 0 and = 0.05. The energetic parameters are E aa = ab = 0 (curve 1), E fi, = 0, ab = -1 (curve 2) and Eaa = ab = (curve 3). The desorption rate is not affected by Eab (curve 2) whereas attractive interactions between the A particles decrease the desorption rate. For smaller values of Tco no A particles exist on the surface.
