Abstract
In this paper, a method for the determination of the sp(3)/sp(2) ratio for carbon atoms in a-C:H films is presented. First, the infrared ana lysis of the films is performed and the sp(3)/sp(2) ratio for the hydr ogenated carbon atoms is determined. From this value, and making diffe rent assumptions for the different types of a-C:H (graphite-, diamond- or polymer-like), the overall sp(3)/sp(2) ratio is determined. The re sults obtained are in good agreement with NMR data for the types of a- C:H considered.
