Recent nuclear magnetic resonance experiments on protons in hydrogenated amorphous silicon sa-Si:Hd by T. Su, P. C. Taylor, G. Ganguly, and D. E. Carlson fPhys. Rev. Lett.89, 015502s2002dg have shown that light exposure leads to structures involving two protons separated by 2.3±0.2 Å. In this report, using supercell models of a-Si:H, we show that SiH2 configurations in the solid state are consistent with these observations. We find an average proton distance of 2.39 Å for SiH 2 structures… CONTINUE READING
