考虑六方格子衬底上的沉积粒子扩散过程,本文利用Monte Carlo方法对自组织生长岛的面密度进行了研究.模拟得到了岛的生长形貌图,结果表明生长的岛数与扩散步数成反比且存在最大23%岛覆盖率,由岛的覆盖率可估算量子点分布的最大面密度.

The studies of the island area density on the six-lattices substrate by using Monte Carlo method are reported in this paper. The model based on the adatoms diffusion process has been obtained in the simulation for the growth of self-organized islands. The results show that the islands coverage has the maximum growth area coverage of 23%. The maximal theoretical area density of quantum dots can be estimated theoretically according to the coverage.
