(a) SEM image of single crystal (inset: HRTEM image) of nanowires arranged in a crossover geometry and (b) SEM image of ZnO nanowires in parallel geometry.
SPR of crossed nanowires and Ag nanoshells.
Comparison of SERS signal for highly crossed nanowires and nanowires, exhibiting few crossings. The Raman signal shown is for a similar nanowire density.
(Color) Finite element simulation of the electric field near two diameter Ag obliquely crossed wires separated by in air, in response to wavelength light polarized in the direction.
