Near-field Raman spectroscopy using a sharp metal tip.
نویسندگان
چکیده
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 observed Raman enhancement factors.

Comparative study of atomic force mode and tunneling mode tip-enhanced Raman spectroscopy
In Tip-Enhanced Raman Spectroscopy (TERS) a metal (or metallized) sharp tip is used to enhance the electromagnetic field by a localized surface-plasmon excitation. Two different modes – atomic force mode (AFM) and scanning tunneling mode (STM) – together with their respective types of probe tips are used in TERS experiments. We have compared the efficiency in enhancing the Raman signal on a thi...
متن کاملNear-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...

The origin of Raman spectroscopy dates back to the early 20th century. Theoretical predictions1 postulated that photons should inelastically scatter from molecules in analogy to the Compton scattering of X-rays. In 1928, Raman and Krishnan2 provided the first experimental evidence for such scattering events. Targeting a solution of chloroform with a beam of spectrally filtered sunlight, they de...

Spectroscopic methods with high spatial resolution are essential for understanding the physical and chemical properties of nanoscale materials including biological proteins, quantum structures and nanocomposite materials. In this paper, we describe microscopic techniques which rely on the enhanced electric field near a sharp, laser-irradiated metal tip. This confined light-source can be used fo...
متن کاملSurface enhancement in near-field Raman spectroscopy
The intensity and selection rules of Raman spectra change as a metal surface approaches the sample. We study the distance dependence of the new Raman modes with a near-field scanning optical microscope ~NSOM!. The metal-coated NSOM probe provides localized illumination of a metal surface with good distance control. Spectra are measured as the probe approaches the surface, and the changes elucid...
