Research Abstract

Nano-scale spectroscopy of scanning near-field optical microscope (SNOM) and its high-functionality have been investigated as follows.
1. Near-field effects on polystyrene fine-particle array crystals.
(1) SNOM transmission images were reversed as the wavelength of light crossed the photonic-band resonance of the crystal. The patterns were reproduced by calculation.
(2) The SNOM patterns resembled both for illumination and collection modes since the probe mainly picked up the polarization component parallel to the layer.
(3) The SNOM patterns varied drastically depending on the particle radius, aperture size of SNOM probe and wavelength of light. This fact indicates the effectiveness of using the array crystal as a standard measure of the quality of the probe.
(4) The bandwidth of the photonic bands becomes narrow as the particle size reduces with keeping the same inter-particle distance. The inter-particle overlapping of the WG modes of each particle is essential as in the case of the form … More ation of electronic bands.
2. Development of high functionality
(1) Quartz oscillator was used to control the probe height instead of laser control.
(2) SNOM apparatus was put in a cryostat and the measurement was done at 100K.
(3) A straight fiber probe made possible the polarization measurement and successively applied for the measurement of crystal orientation of sub-micron crystals of perylene.
(4) UV measurements with use of silica fiber and flexible measurements with using the probes of small stiffness constant were both realized.
3. Nano-scale processing by light
(1) Holes of less than 100nm in diameter and a few tens of nm in depth were made by irradiation of near-field light on the surface of perylene microcrystals. The processing became possible due to the photo-excitation of surface excitons, that accelerate the desorption or dissociation of constituent molecules on the surface.
(2) Temporal topographic change after the photo-processing was investigated by AFM. Average diffusion speed of the surface molecules were about 2〜3nm/min. Less
