In order to observe the lattice vibration in nano-scale, we have developed a new type of scanning
near-eld Raman scattering system by combining scanning atomic force microscopy with microprobed
Raman scattering spectroscopy. A special designed cantilever with aperture of about 150
nm in diameter was used both as an illumination nano-source and a nano-detector of scattering
light. Near-eld Raman spectra of the 1 internal modes of MoO4 molecules in the GMO single
crystal were observed at its cleavage surface at room temperature. The spectrum is compared with
that obtained by a conventional Raman microscope. With using the piezoelectric stage, the sample
was scanned in nano-scale and near-eld Raman spectra were observed as a function of position on
the surface.
