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。
