摘要：

We have studied the effect of excess charge on the bond strength in the silanes SiH4 and Si2H6 to assess whether charge trapping in a solid-state lattice might promote the technologically important photodegradation of amorphous silicon alloys (the Staebler-Wronski effect). The calculations indicate that both positive and negative charges reduce the strength of Si-H and Si-Si bonds considerably, to the point where they may be broken easily by visible or even infrared light.
