| Outline of Final Research Achievements |
An intense laser probe about 10 micrometer in diameter was formed on a specimen under transmission electron microscopy (TEM). With the light probe, micro-Raman spectroscopy under TEM, with a spatial resolution of the order of 10 micrometer simultaneously with an energy resolution of 6 meV, was demonstrated.
A metal tip covered with silver nanoparticles (60 nanometer in diameter) was placed on an arbitrary position in the above-mentioned laser probe, and a near-field light was induced at the apex by a tip-enhanced effect. However, the intensity of the near-field light was too low to demonstrate near-field Raman spectroscopy under TEM with a spatial resolution of 60 nanometer.
