Carbon nitride deposited using energetic species: a review on xps studies
TLDR
In this paper, a review of x-ray photoelectron spectroscopy studies on carbon nitride (CN) is presented, based on results obtained from CN thin films prepared by mass selected ion-beam deposition.Abstract:
This paper reviews x-ray photoelectron spectroscopy studies on carbon nitride (CN) and reports on results obtained from CN thin films prepared by mass selected ion-beam deposition. The core-level spectra of samples deposited at room temperature show that nitrogen is incorporated into the amorphous network in two different bonding configurations; carbon has three main bonding configurations whose relative contributions vary as a function of the nitrogen content. For samples deposited at elevated temperatures an ordering of the amorphous CN network towards a crystalline graphitelike structure is observed. Furthermore, both deposition at elevated temperatures (350 \ifmmode^\circ\else\textdegree\fi{}C) and post-deposition ion irradiation have a strong influence on the bonding configuration in the CN films. Based on these results and the results reported in the reviewed literature a picture of the microstructure of carbon nitride deposited using energetic species is developed.read more

The search for novel, superhard materials
TL;DR: The recent development in the field of superhard materials with Vickers hardness of ⩾40 GPa is reviewed in this article, where two basic approaches are outlined including the intrinsic superhard material, such as diamond, cubic boron nitride, C3N4, carbonitrides, etc. and extrinsic, nanostructured materials for which superhardness is achieved by an appropriate design of their microstructure.

Interpretation of infrared and Raman spectra of amorphous carbon nitrides
TL;DR: In this paper, a general framework for the interpretation of infrared and Raman spectra of amorphous carbon nitrides is presented, which can be used to explain the large dynamic charge of the more delocalized bonding which occurs in more than two bonded networks.
