Figure 3From: Electrical and optical properties of binary CN x nanocone arrays synthesized by plasma-assisted reaction depositionAbsorption spectra of the CNNC arrays grown at different CH 4 /N 2 feeding gas ratios. The CH4/N2 feeding gas ratios were 1/80, 1/40, 1/20, 1/10, and 1/5, respectively.Back to article page
