Image of FIG. 1.
FIG. 1.

(a) and (b) SEM images of the yellow sponge-like products, suggesting a wire-like morphology. Some particles at the tip of wires were observed.

Image of FIG. 2.
FIG. 2.

(a) Typical low-magnification TEM image of several nanocables. (b) and (c) magnified TEM images of individual nanocable. (d) EDX spectrum taken from an individual nanocable, suggesting the nanocable is composed of CdS, S, Si, and very little oxygen. The tiny Cu peak came from the TEM grid.

Image of FIG. 3.
FIG. 3.

Elemental maps of Cd, S, Si, and O, taken at the cadmium edge , sulfur edge , silicon edge , and oxygen edge , respectively.

Image of FIG. 4.
FIG. 4.

SAED patterns taken from a nanocable (a) and the exposed core region (b) existing in an asymmetric rupture of a nanocable. The diffraction spot pattern indicates a hexagonal wurtzite structure of crystalline CdS core, and the diffraction ring indicates the outer amorphous Si layer. (c) HRTEM image of the interface between the crystalline CdS core and amorphous Si sheath, revealing a clear core∕sheath interface. (d) An enlargement HRTEM image of the boxed region in (c).

Image of FIG. 5.
FIG. 5.

(a) and (b) PL spectra of naked CdS nanowires and nanocables at room temperature. The excitation wavelength is .
