introduction
Single-walled carbon nanotubes are the simplest structure of carbon nanotubes, with unique electrical, optical and mechanical properties in microelectronic devices and nano
Composite materials and other fields have broad application prospects. Raman spectroscopy is the most common, non-destructive and rapid experimental technique for characterizing single-walled carbon nanotubes
One of the means. Because single-walled carbon nanotubes have a unique one-dimensional nanostructures, their Raman spectra exhibit many new physical phenomena,
Strong Raman effect is one of the most important phenomena in Raman spectroscopy of single-walled carbon nanotubes. The Raman spectra of single-walled carbon nanotubes have several characteristics
peak. Some of the parameters of the characteristic peaks, such as peak, peak, or intensity, can be used to quantitatively or qualitatively characterize single-walled carbon nanotube samples,
The frequency of the single-walled carbon nanotubes can be calculated for the determined laser wavelength, according to the electron transition energy of single-walled carbon nanotubes and
Single-walled carbon nanotube diameter and the diameter of the sample, combined with the G-shaped peak shape can determine the conductivity of single-walled carbon nanotubes; according to D
The ratio of the modulus to the G mode, and the strength of the G mode can be used to evaluate the amorphous carbon and the defect content in the carbon nanotubes. The development of this standard will be
And provide technical guidance for the production and research of single-walled carbon nanotubes.
