Abstract
We present a study of the structure of a-Si1-xCx:H alloys by wide-angl e x-ray scattering. By carefully analyzing the radial distribution fun ctions and comparing with previous extended x-ray-absorption finestruc ture measurements, we provide a detailed and quantitative description of local bonding around Si and C atoms. Among the results presented, m ost noteworthy are constant interatomic distances in first and second shells and the detection of a strong tendency for chemical order.
