摘要

We have deconvoluted the dangling bond ESR spectra into two components, one due to normal dangling bonds and the other to hydrogen-related dangling bonds in glow-discharge a-Si:H samples. The isotropic and anisotropic hyperfine interaction constants due to a hydrogen nucleus are estimated from the deconvolution. It is found that they are mutually related through a simple theoretical expression. The distance between the dangling bond site and hydrogen in the hydrogen-related dangling bond and relative densities of the above two types of dangling bonds are also estimated and discussed in correlation with the hydrogen content.
