Atomic force microscopy is used to examine the surface morphology of the 3-monolayer InAs. It's found that the evolution of surface morphology with increasing the GaAsSb thickness can be classified into 3 stages: random distribution of InAs quantum dots, space-selective growth of InAs quantum dots on cross-hatching surface, and purely cross-hatching surface.

最后，由原子力显微镜分析，让我们观察到样品表面的InAs奈米结构的分布型态：(1)随机分布，(2)在田埂状(cross-hatching)的表面上选择性的成长，(3)奈米结构渐渐地消失，最后仅剩田埂状的表面型态。

Using unrelated algorithms is an important step in allowing the random data to be used to make cryptanalysis more difficult.

使用无关的算法是一个重要的步骤，让随机数据被用来作密码分析更加困难。
