Laser ablation in liquids: Applications in the synthesis of nanocrystals

“…They [239] suggested that covalent C-N solids could have bulk modulus comparable to diamond and hence are a good candidate for hard materials in technological applications. These results have led to theoretical calculations and experimental efforts to gain this compound [240][241][242][243][244][245][246][247][248][249][250]. By theoretical calculation, Teter and Hemly [249] reported five forms of C 3 N 4 , namely a-C 3 N 4 , b-C 3 N 4 , pseudocubic-C 3 N 4 , cubic-C 3 N 4 , and graphite-C 3 N 4 .…”

Deposition and Tribology of Carbon and Boron Nitride Nanoperiod Multilayer Hard and Solid Lubricating Films

“…As a super hard film, the superlattice film laminated with www.intechopen.com New Tribological Ways 72 thin layers by several nanometers was investigated. Concretely, superlattice films such as CNx/TiN (Li et al, 1995) and TiN/AlN (Nakayama, 1997) were performed. In our studies, the (CN/BN)n multilayer film was proposed to deposit using boron nitride and carbon nitride layer by layer to form a novel superlattice film and its properties were investigated.…”

ELECTRONIC STRUCTURE OF SIX PHASES OF C3N4: A THEORETICAL APPROACH

“…Up to now the results reported only show the existence of nanocrystals (β and α phases) embedded in an amorphous film. [4][5][6][7][8][9][10][11][12][13][14][15] Chen et al studying the effect of methane concentration found that their samples had a mixture of β and α phases of C 3 N 4 and tetragonal and monoclinic phases of C-N. 4 On the theoretical side, several studies of the electronic structure and structural properties of the beta phase have been done. Corkill and Cohen 16 calculated the quasiparticle band gap of the beta phase using the GW approximation, they found an indirect band gap of 6.4 eV and a direct gap at Γ of 6.75 eV.…”
