内容記述 | For the both of Kinetic Monte-Carlo (KMC) and rate equations (RE) based on irreversible sub monolayer growth of point islands in substrate spatial dimension d = 2, 3 and 4 as the limit R , I find that monomer density N1 and island density N have N1 = −1 ˆ() and N = −1 ˆN (), where R is the ratio of the monomer diffusion rate to the deposition rate, is coverage and is the scaling factor determined by the detail of the system. The function ˆ and ˆN are universal functions independent of R and d, and calculated in the minimal model for submonolayer epitaxy by Tang [L. -H. Tang, J. Phys. I France 3, 935 (1993)]. As result, = (R)1/2 was obtained for the both KMC and RE in d = 2, 3 and 4, where is the capture number of diffusing monomer. Finally, for RE in d > 4 as the limit, I show N1 and N have function form as same as the form in d 4. |
