Amorphous Carbon Nitride

AbstractRecently there has been very much interest in understanding the structure of amorphous carbon nitride thin films, it has been shown that the introduction of nitrogen in amorphous carbon leads to better properties. In this paper we use four different cluster to study the changes in the local density of states at the carbon and nitrogen sites introduced by different environments. The method used is a SCF Hartree-Fock using pseudo potentials. We have considered carbons with sp3 and nitrogens with sp2 and sp3 hybridization. The results show that when N occupies a tetrahedral position (sp3) it introduces a localized state in the gap, while in the sp2 configuration, it introduces states near the edges of the bands.

Substrate Temperatures

Amorphous carbon nitride films ( a-CN x) were deposited by pulsed laser deposition of camphoric carbon target with different substrate temperatures (ST). The influence of ST on the synthesis of a-CN x films was investigated. The nitrogen-to-carbon (N/C) and oxygen-to-carbon (O/C) atomic ratios, bonding state, and microstructure of the deposited a-CN x films were characterized by X-ray photoelectron spectroscopy and were confirmed by other standard measurement techniques. The bonding states between C and N , and C and O in the deposited films were found to be significantly influenced by ST during the deposition process. The N/C and O/C atomic ratios of the a-CN x films reached the maximum value at 400°C. ST of 400°C was proposed to promote the desired sp 3-hybridized C and the C 3 N 4 phase. The C–N bonding of C–N , C=N and C≡N were observed in the films.
