| Research Abstract |
Scanning confocal electron microscopy (SCEM) is a promising 3D imaging techniques by electron microscopy, which enables to improve the depth resolution by rejecting most of electrons from an out-of-focal plane in an object using a pinhole aperture. We developed a stage-scanning system for SCEM, by which only the specimen moves three-dimensionally while maintaining constant lens configuration. Then, we proposed annular dark-field SCEM that use scattered electrons by using an annular aperture to block direct beams. Finally, we succeeded in the improvement of the depth resolution and 3D imaging of carbon nanostructures and catalytic nanoparticles on support materials.
