Image of FIG. 1.
FIG. 1.

The low magnification TEM images and the optical extinction spectra of the three samples collected from different temperature zones, i.e., 1100, 1000, and .

FIG. 2.

TEM BF images of (a) core/shell spherical particle and [(c) and (e)] nanocables of different sizes. The corresponding energy filtered images (using the Si bulk plasmon) of (b) core/shell spherical particle, (d) nanocable of Si core diameter, and (f) nanocable of Si core diameter. [(g)–(i)] SREELS images of the three samples. [(j)–(l)] The SREEL spectra extracted from the corresponding SREELS images.

FIG. 3.

Schematics of charge distributions on objects with different geometries: (a) sphere and (c) cylinder. (b) Comparison of calculated and experimental EEL spectra of core shell structure with spherical geometry and (d) cylindrical geometry. (e) The EFTEM images of a single nanocable in the tip region, imaged at energy losses of 17, 8, and 4 eV using a 2 eV width slit.
