If do not have Sb as the situation of surfactant: this moment, the potential barrier of step edge was more much higher than diffusion barrier, make additional edge potential barrier (potential barrier that atom falls step deducts the potential barrier of diffusion into the surface) quite big, the adatom on the upper table surface is not easy to jump off.The reason that additional edge potential barrier produces is: when atom jumped off step, its ligancy certainly will reduce, so potential barrier can appear in this process.The introducing of Sb is increased diffusion barrier, has reduced the mobility of Ag adatom on table top, and additional edge potential barrier is reduced.Island density is increased, and the probability that the adatom at step place is jumped off is close with the diffusion probability on the table top.Secondly the introducing of Sb makes atom along step edge diffusion difficulty, makes the edge very irregular, and a lot of kinkings are namely arranged on the step.In general there is strain relaxation in kinking place of step, and the potential barrier of jumping off in kinking place can decrease.Again, the density on the island of increase reduces the size on island, or the branch on island is narrowed down, and these can increase the probability that the Ag adatom arrives step.These effects all make the Ag film growth be more prone to two-dimensional growth, make the Ag layer growth more even, fine and close.
