TEM images and EDS spectra of cobalt silicide nanowires. (a) Low-magnification, (b) high-resolution TEM images and (c) EDS spectrum of CoSi nanowires grown at 850°C ~ 880°C. The inset in (b) shows the corresponding selected area diffraction pattern with a zone axis of [0-11]. (d) Low-magnification, (e) high-resolution TEM images and (f) EDS spectrum of Co₂Si nanowires grown at 880°C ~ 900°C. The inset in (e) shows the corresponding selected area diffraction pattern with a zone axis of [1–30].
