Superhard and Elastic Carbon Nitride Thin Films Having Fullerenelike Microstructure

CF : A first-principles study of structural patterns arising during synthetic growth

“…The substitution of C by, e.g., N, P or S [7] in FL compounds promotes defects such as combinations of pentagons [4,6,7], thus leading to bent graphene sheets and crosslinkages resulting from sp 3 -hybridization between the C atoms within the sp 2 -coordinated sheets. The deposition method of choice for these compounds is reactive magnetron sputtering.…”

“…Carbon-based fullerene-like (FL) compounds represent a novel class of thin solid film materials offering remarkable mechanical properties such as resilience and hardness [1,2] as in carbon nitride (CN x ) [1,3,4] and phosphorus carbide (CP x ) [2,5,6]. The substitution of C by, e.g., N, P or S [7] in FL compounds promotes defects such as combinations of pentagons [4,6,7], thus leading to bent graphene sheets and crosslinkages resulting from sp 3 -hybridization between the C atoms within the sp 2 -coordinated sheets.…”

Carbon Fluoride, CFx: Structural Diversity as Predicted by First Principles

“…In order to tailor the properties of nanostructured carbon-based thin films for desired technological applications, other elements such as nitrogen, 4,[8][9][10] phosphorus, [11][12][13] sulfur 8,[14][15][16] and fluorine [17][18][19][20][21][22][23][24][25] are often incorporated in the carbon matrix at concentrations between 0-30 at.%.…”

Spectroscopic ellipsometry characterization of amorphous carbon and amorphous, graphitic and fullerene-like carbon nitride thin films

“…as tribological coatings [3], as protective layers on magnetic hard disks [4], as filler in electrical conductive adhesives [5], and as a biomaterial [6,7]. In the context of biomaterials, one group of carbon-based materials should be mentioned in particular, the fullerene-like CN x, discovered in 1995 [8][9][10]. It is a nano-scaled material consisting of bent and intersecting, cross-linked nitrogen containing graphene sheets, exhibiting a combination of high hardness and extreme elasticity and might be a candidate aimed e.g.…”
