“…For example, CNTs are CVD grown on Si or metallic substrates precoated with a CVD diamond film decorated with catalytic metal particles, therefore nucleating and growing the tube structures. 7,10 In these studies, the CNTs are grown by the so-called base growth method where the metal catalyst particles remain attached to the diamond surface because of strong CNT/diamond adhesion forces. 11,12 Disadvantageously, the remaining metal particles in the final multilayer composite structure may negatively affect their electromechanical properties.…”

Given the specific properties of each carbon allotrope such as high electrical/thermal conductivity of multiwall carbon nanotubes (MWCNT) and extreme hardness and high inertness of nanocrystalline diamond (NCD), the integration of both carbon phases is highly desirable. Therefore, in the present work, buckypapers were produced from MWCNT suspensions and were used as free-standing substrates to be coated with NCD by microwave plasma chemical vapor deposition (MPCVD). The integration of both allotropes was successfully achieved, the CNTs being preserved after diamond growth as confirmed by μ-Raman spectroscopy and scanning electron microscopy (SEM). Additionally, a good linkage was observed, the CNTs remaining embedded within the NCD matrix, thus reinforcing the interface of the resulting hybrid structure. This was corroborated by bending tests in a modified nanohardness tester. The increase of the Young's modulus from 0.3 to 300 GPa after NCD growth enables the use of this material in a wide range of applications including microelectromechanical systems (MEMS). Additionally, a highly anisotropic electrical resistivity behavior was confirmed: low in-plane values were found for the CNT layer (1.39 × 10(-2) Ω.cm), while high transverse ones were measured for both the NCD coated and uncoated CNT buckypapers (8.13 × 10(5) and 6.18 × 10(2) Ω.cm, respectively).

“…There are a number of carbon-based materials such as diamond, 1) graphite, 2) carbon nanotubes, 3) fullerenes, 4) graphene, 5) carbon nanowires, 6) and amorphous carbon films. [7][8][9][10] To understand the deposition of carbon-based films by a plasma-enhanced chemical vapor deposition (PECVD) method, we have investigated the deposition process using various source molecule as precursors.…”

In situ, real-time infrared absorption spectroscopy in the multiple internal reflection geometry was employed to investigate the evolution of hydrocarbon components deposited during plasma-enhanced chemical vapor deposition with a deuterated benzene source. We detected a peak attributed to the C-D stretching vibration of the deuterated phenyl group, which indicated a mode in which the benzene ring structure is retained on the substrate during the adsorption. The evolution of each peak during the plasma exposure suggests that the addition reaction occurs during the adsorption. Furthermore, we observed that with increasing substrate bias applied, the benzene ring structures in the film were disrupted and the amount of alkane components increased. This addition reaction proceeded on the film surface, regardless of the substrate bias.
