Control of Cross-Sections and Optical Nonlinearity of Pt Nanowires and the Roughness Effect

Figure 1

Schematic cross-sectional shapes of Pt nanowires on MgO(110) substrate fabricated in this study. (a) Pt nanowires are on one face of the facet but are seen to extend beyond the top of the facet. The edge of this extending part has more sharp curvature. (b) Pt nanowires on the two faces of the facet are connected at the top of the facet and its cross-section shape becomes symmetric with respect to the substrate normal.
