Paper Abstract

The interactions between an apertureless metal-coated tip and C-60 molecules have been studied by near-field Raman scattering technique. The electromagnetic and the chemical interaction through the local plasmon polaritons generated at the metallized tip apex provide an enhanced scattering and high spatial resolution much beyond the diffraction limits of the probing light. And additional enhancement under the gap-mode configuration, when C-60 molecules were sandwiched between a thin rough metal layer and metallized tip, was observed. Further, the mechanical interaction between the tip and C-60 molecules were studies by pressurizing C-60 molecules uniaxially by the tip. The photopolymerization of C-60 molecules was found to accelerate under high tip-pressure.
