Aside from fluorescence, surface plasmons (those that are either excited on the metallic surface or localized in a small metallic tip) also provide a method of overcoming the diffraction limit of ...

Advanced imaging techniques have evolved to see beyond the diffraction ... achieved depending on tip sharpness and the confining field strength. The far-field SMACM methods routinely achieve ...

This review focuses on the applications of cutting-edge ultrafast nano-spectroscopy and nano-imaging based on diverse ...

(a) Schematic diagram of the angstrom-beam electron diffraction method. (b) Electron diffraction patterns obtained from amorphous Zr-Ni alloy with different beam sizes. The pattern with 100-nm beam ...
