FIG. 1.

TEM images of an axial heterostructured SiNW taken along the wire growth direction. (a) The B-doped ( -type) SiNW region, (b) the P-doped ( -type) SiNW region, and (c) the intrinsic SiNW region.

FIG. 2.

(a) HRTEM image of the sidewall facets in the B-doped region of the axial heterostructured SiNWs, viewed from the direction, inset: image taken at low magnification and facet angles are indicated. (b) HRTEM image of the facet, inset: Fourier transform of the image. (c) HRSEM image of the sidewall facets in the B-doped region of the axial heterostructured SiNWs.

Image of FIG. 3.
FIG. 3.

(a) Schematic of the 3D structure of a faceted axial heterostructured SiNW in the B-doped region, (b) schematic of the 2D structure viewed along the direction, and (c) schematic showing the side view of the ideal Si{112} surface.

Image of FIG. 4.
FIG. 4.

(a) High-angle annular dark field (HAADF) image of single Au atoms (marked by arrows) in the near-catalyst region of an axial heterostructured SiNW, as a reference for the contrast between Au and Si. (b) High resolution HAADF image of faceted B-doped SiNW region in the same SiNW, viewed from the direction, inset: Fourier transform of the image. (c) TEM image showing the initially grown intrinsic region of a long axial heterostructured SiNW, view from the direction. (d) HRSEM image of the initially grown intrinsic region of a long axial heterostructured SiNW.
