Optical characterization of vertically aligned single-walled carbon nanotube arrays
Here we discuss spectroscopic investigation and characterization of vertically aligned single-walled carbon nanotube (VA-SWNT) arrays, which were synthesized using the alcohol catalytic CVD method [1]. Growth of the VA-SWNTs was monitored using an in situ absorbance measurement [2], which provides information about the growth process. Primary methods employed were Resonance Raman and UV-Vis-NIR...
متن کاملAnisotropic electrical conduction of vertically-aligned single-walled carbon nanotube films
Anisotropic electrical conduction measurements have been carried out for thin films of vertically-aligned single-walled carbon nanotubes (VA-SWCNTs) grown by an alcohol catalytic CVD process. Combined with controlled synthesis and structure characterization by optical spectroscopy, the influence of the aligned structure on the electrical conduction has been identified. The out-of-plane conducti...
متن کاملThe internal structure of vertically aligned single-walled carbon nanotube films
In this study, we investigated the internal structure of ’as-grown’ vertically aligned single-walled carbon nanotube (VA-SWNT) films by cross-sectional transmission electron microscopy (TEM). The VA-SWNTs were produced by the alcohol catalytic CVD method [1, 2], and transferred onto a TEM grid using a hot water technique [3]. The resulting freestanding VA-SWNT film was observed along the alignm...
متن کاملGrowth of vertically aligned single-walled carbon nanotube films on quartz substrates and their optical anisotropy
Films of vertically aligned single-walled carbon nanotubes (SWNTs) with a few μm thickness were grown by catalytic chemical vapor deposition (CVD) on quartz substrates. Low-temperature CVD from ethanol was performed by using densely mono-dispersed Co-Mo catalyst of ≈ 1.0 – 2.0 nm prepared on quartz substrates by a dip-coating method. Continuous reduction of catalysts with Ar/H2 (3% H2) during C...
متن کاملAngular dependent anisotropic terahertz response of vertically aligned multi-walled carbon nanotube arrays with spatial dispersion
Spatial dispersion effect of aligned carbon nanotubes (CNTs) in the terahertz (THz) region has significance for both theoretical and applied consideration due to the unique intrinsically anisotropic physical properties of CNTs. Herein, we report the angular dependent reflection of p-polarized THz wave from vertically aligned multi-walled CNT arrays in both experiment and theory. The spectra ind...
