Abstract

A combination of electron spin resonance and Raman spectroscopy measurements is applied to fully characterise a-C_1-xN_x:H films (x ≤ 20 at.%), grown by plasma decomposition of C₂H₂-N₂ mixtures. The observed decrease in the spin density (8.5 × 10₁₉-1.6 × 10₁₉ cm_-3) when the N content increases is consistent with the decrease in the disorder of the sp² nanostructure evidenced by resonant Raman spectroscopy (at 488 and 514.5 nm excitations), which shows an increase in the I_D/I_G ratio and a narrowing of the D-peak.
