摘要：

The relation between the optical properties of hydrogenated amorphous silicon (a-Si:H) and the hydrogen concentration in the material was studied. A quantitative model is presented that describes the relation between the optical gap, the refractive index, and the hydrogen content of a-Si:H. This model is based on a model for the incorporation of hydrogen in the a-Si:H network, the concept of bond polarizabilities, and the harmonic oscillator approximation. We determined the optical gap and refractive index from reflection and transmission measurements. The hydrogen content was determined by nuclear reaction analysis (NRA). The values obtained from the theoretical model correspond well with our experimental results and correspond also with experimental results from literature.
