Optical properties of the CNx films deposited at various substrate temperatures and deposition time. (a) Optical transmission spectra for the films deposited on glass substrates at different substrate temperatures, with an inset showing the visible light transparency of the films. (b) Tauc plots of CNx films deposited at various substrate temperatures. The inset represents the variation of the optical band gap with substrate temperature. (c) Refractive index as a function of wavelength for the CNx films deposited at various substrate temperatures. (d) Reflection spectra for films deposited at 200 °C and different deposition times (layer thickness), with a reference reflection of a bare silicon wafer.
