So we asked Miles Jacobson, Studio Director at SI Games, to take us through some of the changes you'll want to hear about most...

现在我们就让SI的工作室总监Miles Jacobson 来介绍一些你最想了解的新变化。

The patterns of Reflection high energy electron diffraction from the epitaxial growth of Si-Ge crystal are interpreted basing on the kinetical diffraction theory of crystal.

在晶体衍射理论基础上，利用运动学理论解释了反射式高能电子衍射（reflection high energy electron diffraction， RHEED）在Si-Ge晶体外延生长过程中不同阶段出现的花样。

Similar to the oxidation process of Si(111)-7×7 by water,the gradual insertion of S atom into Si_a-Si_s backbond is possible to occur,and the insertion pathway,which begins with directly destroying Si_a-Si_s backbonds by a foreign H_2S molecule,remains more favorable.However,when H_2S attacks at the Si_a site to split Si_a-Si_s backbond with its S or H atom,there is no distinct thermodynamical and kinetical difference between these two attacking behaviors,whereas Si_a-Si_s backbond is easilier broken when H_2O attacks at the Si_a site with its O atom.This mainly lies in the fact that the electronegativity of oxygen is larger than that of sulfur.

5类似于H_2O对Si(111)-7×7的氧化历程，S原子逐步插入Si_a-Si_s键是可以发生的，且H_2S直接打开Si_a-Si_s键进而使S原子插入的途径仍是动力学上较为有利的，但H_2S以S或H原子进攻Si_a位从而打开Si_a-Si_s键的两种反应机制在动力学和热力学上并没有表现出明显的差别，而当H_2O以O原子进攻Si_a位时，Si_a-Si_s键则较容易断裂，这应归因于O的电负性比S大。
