Reduction of single-walled carbon nanotube diameter to sub-nm via feedstock
Vertically aligned single-walled carbon nanotube arrays were synthesized from dip-coated binary Co/Mo catalyst by no-flow chemical vapor deposition from either pure ethanol or acetonitrile as carbon feedstock. By changing to acetonitrile the mean diameter was reduced from 2.1 nm to less than 1.0 nm despite using identically prepared catalyst. The demonstrated diameter control on flat substrates...
متن کاملFitting Single-Walled Carbon Nanotube Optical Spectra
In this work, a comprehensive methodology for the fitting of single-walled carbon nanotube absorption spectra is presented. Different approaches to background subtraction, choice of line profile, and calculation of full width at half-maximum are discussed both in the context of previous literature and the contemporary understanding of carbon nanotube photophysics. The fitting is improved by the...
متن کاملBolometric Properties of Semiconducting and Metallic Single-Walled Carbon Nanotube Composite Films
Single-walled carbon nanotubes (SWNTs) have shown interesting bolometric properties, making them good candidates for the detection of infrared and terahertz radiation. However, little has been reported on the bolometric characteristics of SWNT as a function of their chirality or the possible influence of composite morphology on these properties. The separation of SWNTs based on chirality allows...
متن کاملCharge-compensated, semiconducting single-walled carbon nanotube thin film as an electrically configurable optical medium
A two-terminal semiconducting single-walled carbon nanotube (SC-SWNT) film in contact with an ionic liquid allows the realization of an extremely high density of holes, inducing a strong position-dependent electromodulation of the interband and excitonic transitions as a result of the position-dependent shift of the SWNT Fermi level. Electrical control of the optical transmission suggests appli...
متن کاملInvestigation of ultraviolet optical properties of semiconducting-enriched and metal-enriched single-walled carbon nanotube networks using spectroscopic ellipsometry.
The ultraviolet optical properties of semiconducting-enriched and metallic-enriched single-walled carbon nanotube (semi-enriched and m-enriched SWCNT) networks were studied using spectroscopic ellipsometry. According to calculated energy loss function, the energy loss peak assigned to the maximum intensity of π-plasmon energy was found to increase from 4.5 eV to 5.0 eV as SWCNT network composit...
