Finding a needle in a haystack: tip-enhanced Raman scattering for studying carbon nanotubes mixtures

چکیده

Tip-enhanced Raman spectroscopy (TERS) has emerged as a powerful analytical tool for measuring chemical images with nanometer spatial resolution. In this paper, the application of TERS to study differentiation of SWCNT with 14 nm spatial resolution is demonstrated by the measurement of a mixture of two different types of SWCNT as the model sample. The results demonstrate that TERS is a viable tool for the detection and localisation of different SWCNT and amorphous carbon in mixed SWCNT based on the spectral differences in the radial breathing mode and the D bands.

Tip-enhanced Raman spectroscopic imaging of localized defects in carbon nanotubes

We used tip-enhanced Raman spectroscopy to study defect induced D-band Raman scattering in metallic single-walled carbon nanotubes with a spatial resolution of 15 nm. The spatial extent of the D-band signal in the vicinity of localized defects is visualized and found to be about 2 nm only. Using the strong optical fields underneath the tip, we photogenerate localized defects and derive a relati...

Near-field Raman Spectroscopy of Individual Single-walled Carbon Nanotubes

Near-field Raman spectroscopy with high spatial resolution is used to study singlewalled carbon nanotubes (SWNT) within dense samples. A sharp, laser irradiated metal tip acts as a near-field excitation source causing an enhanced Raman signal within close proximity of the tip. We present optical images of different Raman modes with a spatial resolution better than 15 nm. Local spectroscopy allo...

Tip-enhanced Raman mapping with top-illumination AFM.

Tip-enhanced Raman mapping is a powerful, emerging technique that offers rich chemical information and high spatial resolution. Currently, most of the successes in tip-enhanced Raman scattering (TERS) measurements are based on the inverted configuration where tips and laser are approaching the sample from opposite sides. This results in the limitation of measurement for transparent samples only...
