The role of hydrogen in the Staebler-Wronski effect of a-Si:H

We have studied the effects of hydrogen concentration and hydrogen configuration on the light-induced change, called Staebler-Wronski effect, in a-Si:H. A strong correlation is found between the light-induced spin density and the fractional hydrogen content evolved at low annealing temperature. The...

Zusammenfassung:	We have studied the effects of hydrogen concentration and hydrogen configuration on the light-induced change, called Staebler-Wronski effect, in a-Si:H. A strong correlation is found between the light-induced spin density and the fractional hydrogen content evolved at low annealing temperature. The light-induced defects are supposed to be created through the breaking of weak Si-Si bonds in the regions containing clustered SiH or SiH 2 bonds.
