“…The characteristic wavelengths in figure 6(b) are representative of bonds reported for boron oxide; a wide peak centered at about 3350 cm −1 for stretching of O-H bonds and a sharp asymmetric peak at about 1196 cm −1 representative of B-O deformation. Boron carbide was eliminated as the prominent secondary phase since the broad shoulder around 1050 cm −1 characteristic of boron carbide phonons is not present [41,42]. Another condition that is not met for the formation of prevalent boron carbide impurities during the CVD procedure is a high growth temperature (>1000°C) [43,44].…”

Few-walled carbon nanotubes offer a unique marriage of graphitic quality and robustness to ink-processing; however, doping procedures that may alter the band structure of these few-walled nanotubes are still lacking. This report introduces a novel solution-injected chemical vapor deposition growth process to fabricate the first boron-doped few-walled carbon nanotubes (B-FWNTs) reported in literature, which may have extensive applications in battery devices. A comprehensive characterization of the as-grown B-FWNTs confirms successful boron substitution in the graphitic lattice, and reveals varying growth parameters impact the structural properties of B-FWNT yield. An investigation into the optimal growth purification parameters and ink-making procedures was also conducted. This study introduces the first process technique to successfully grow intrinsically p-doped FWNTs, and provides the first investigation into the impact factors of the growth parameters, purification steps, and ink-making processes on the structural properties of the B-FWNTs and the electrical properties of the resulting spray-coated thin-film electrodes.

“…In C 3 N 4 , the first set of N-atoms are bonded to 3-coordinated C atoms (sp 2 configuration), and then C atoms are bonded with a 2-coordinated second set of N atoms in the triazine ring (sp 2 hybridization). In this B–C–N triangle exist the hardest materials known – diamond, followed by cubic BN (c-BN) and B 4 C. 26 The atomic similarity of B, C and N elements leads to the formation of BCN ternary compounds within the triangle. 27 c-BCN exhibits super hardness by combining the properties of diamond and c-BN.…”

“…Thin films were synthesized by pulsed DC magnetron sputtering from BN + C (Martinez et al, 2002) or B 4 C (Johansson et al, 1996;Freire et al, 2001;Reigada et al, 2001;Chen et al, 2006) or B 4 C + C (Xu et al, 2006a(Xu et al, , 2006b) targets in Ar/N 2 atmosphere. Effects of target power, target pulse frequency, substrate bias and pulse frequency on surface roughness were studied.…”
