“…all the samples, but accurate determination of the composition of the nanorods by this method is not possible at present time. For the ECR-PECVD deposited buffer layers, Rutherford back-scattering spectroscopy (RBS) was employed to determine their compositions [37,38]. It was found that all the SiC x N y ®lms exhibited an N content very close to 57 at.% while the [C]/[Si] ratio varied from 0 to 1, depending on the process gas compositions.…”
