Image of FIG. 1.
FIG. 1.

(a) SEM image of the product showing the morphologies of Au(Si) filled nanotubes. The fillings inside nanotubes can be observed. (b) XRD spectrum of a sample indicating the presence of and Au. (c) Schematic showing the experimental procedures and physical process of the growth, (I) Si (001) substrate was coated with Au film, (II) the heated Au film formed Au–Si alloy nanodots above Au–Si eutectic point, [(III) and (IV)] the alloy nanodots served as a catalyst for the growth of nanotube. Through capillarity attraction, Au(Si) was drawn into the nanotube.

Image of FIG. 2.
FIG. 2.

(a) TEM image of an open end Au filled nanotube. (b) Energy-dispersive spectra indicating the outer shell and filling are and Au(Si), respectively. The amount of Si in Au–Si alloy is . [(c and d)] Different types of Au(Si) fillings in nanotubes. The fillings could be closed at one end or both ends. (e) High resolution TEM image of a nanotube. The fringe spacing is corresponding to set of planes.

Image of FIG. 3.
FIG. 3.

(a) TEM image of a selected nanotube before heating. (b) Distance of the Au filling to the top of the cavity during heating as a function of temperature. (c) TEM images of an Au-filled nanotube during heating at different temperatures.
