Structure of Hydrogen in Microcrystalline and Amorphous Silicon: an NMR Comparison
Published online by Cambridge University Press: 26 February 2011
Abstract
Hydrogen NMR data on three microcrystalline silicon samples grown by plasma decomposition using different H2/SiH4 gas ratios are examined. A decrease of the total atomic percent hydrogen content from 12 at.% to 6 at.% is seen as the gas ratio is reduced from 98/1 to 20/1. 20 to 40% of this total hydrogen content is determined to be non-bonded molecular hydrogen. In addition, evidence for SiH2 units is seen in the spectrum.
