Monte-Carlo simulation fractional time stepping

Fig. 17 A series of snapshots of a dynamic Monte-Carlo simulation after a negative-going potential step to 20 mV below the transition between the low coverage and mixed X. 3) layer (peakAi). Cu is represented by the filled circles (.), sulfate by a triangle (A), and the unoccupied sites are open circles (.). After the step, a fraction of sulfate desorbs, but the remaining sulfate combines with the newly adsorbed copper to form a loose domain. With time, this domain fills in and grows. The MC-current response reproduces qualitatively the monotonically decreasing experimental transient in panel Ai, Fig. 16 (with permission by P. A. Rikvold, Ref [359], copyright 1999, The Electrochemical Society).
