Low-Pressure CVD of Carbon Nitride Using Triazine-Containing Precursors

“…The layers deposited from this system under the above conditions are referred to as CN x of type B. 2 . The results obtained by X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES) are very similar, and they show that layers deposited in this temperature range consist mainly of C and N in a ratio N/C~1.…”

Tuning of gallery heights in a crystalline 2D carbon nitride network

“…[20][21][22][23] Sundermeyer performed organic chemistry in molten salts in the 1960s, pointing out the good solvating properties of the eutectic mixture of LiCl and KCl with respect to nitrides, carbides, cyanides, cyanates and thiocyanates. 24,25 Inorganic salt melts have also been utilised for the synthesis of extended, covalently bonded, organic frameworks.…”

Deposition of Diamond-Like Superhard Materials in the B/C/N System

“…However, despite all efforts it turned out impossible up to now to develop a method for the reproducible deposition of b-C 3 N 4 . In quite a number of papers, successful b-C 3 N 4 growth has been claimed; however, as discussed in [14,65,71,72], these identifications are in most cases more than doubtful although in quite a few number of experiments the presence of b-C 3 N 4 nanoparticles in an amorphous matrix cannot be excluded [73,74]. Up to now, the carbon nitride films obtained by almost all techniques suffer from three major problems [3,75]: (i) compared to b-C 3 N 4 , the films are seriously nitrogen deficient (20 to 40% nitrogen instead of 57%); (ii) the films are not crystalline but amorphous (in some cases with embedded nanocrystals); (iii) the films do not possess the desired sp 3 bonding environment but consist of a mixture of sp 3 , sp 2 and sp bonded carbon.…”
