Near-field imaging and spectroscopy of electronic states in single-walled carbon nanotubes
نویسندگان
چکیده
Near-field photoluminescence spectroscopy was used to study the electronic properties of semiconducting Single-Walled Carbon Nanotubes in different environments. A sharp laser-illuminated metal tip was raster scanned over the sample and served as a strongly confined excitation source. We observed localization of photoluminescence and variations of emission energies along nanotubes on a length scale of about 30 nm.

Functionalization of the Single-walled Carbon Nanotubes by Sulfur Dioxide and Electric Field Effect, a Theoretical Study on the Mechanism
In this study, kinetics and mechanism of the sulfur dioxide adsorption on the single-walled carbon nanotubes (CNT) are investigated. Three single-walled carbon nanotubes, including the armchair (6,6), chiral (6,5) and zigzag (6,0) CNTs were chosen as the models and the different orientations of SO2 molecule relative to the CNT axis were considered. The B3LYP functional within the 6-3...
متن کاملNear-field Raman spectroscopy using a sharp metal tip.
Near-field Raman spectroscopy with a spatial resolution of 20 nm is demonstrated by raster scanning a sharp metal tip over the sample surface. The method is used to image vibrational modes of single-walled carbon nanotubes. By combining optical and topographical signals rendered by the single-walled carbon nanotubes, we can separate near-field and far-field contributions and quantify the observ...
متن کاملHigh-resolution near-field Raman microscopy of single-walled carbon nanotubes.
We present near-field Raman spectroscopy and imaging of single isolated single-walled carbon nanotubes with a spatial resolution of approximately 25 nm. The near-field origin of the image contrast is confirmed by the measured dependence of the Raman scattering signal on tip-sample distance and the unique polarization properties. The method is used to study local variations in the Raman spectrum...

The electronic densities of states of atomically resolved single-walled carbon nanotubes have been investigated using scanning tunneling microscopy. Peaks in the density of states due to the one-dimensional nanotube band structure have been characterized and compared with tight-binding calculations. In addition, tunneling spectroscopy measurements recorded along the axis of an atomically resolv...
