Control of Cross-Sections and Optical Nonlinearity of Pt Nanowires and the Roughness Effect
Figure 5
The cross-sectional TEM images of Pt nanowires showing (a) elliptic and (b) symmetric boomerang shapes on the MgO(110) faceted substrates. The MgO substrate is seen in the lower part of each panel. Two arrows indicate the wave vectors, and , of the incident and SHG light beams for , respectively.
