Long Wavelength Plasmonic Absorption Enhancement in Silicon Using Optical Lithography Compatible Core-Shell-Type Nanowires

Figure 3

Power absorption spectra in silver (traces (a) and (c)) and silicon (traces (b) and (d)) for the core-shell and half-shell nanowires. Absorption in bare silicon without nanowire is shown in (trace (e)). This trace was scaled up by 5 times, and absorption in silver was downscaled by 10 times. Power absorption was normalized with respect to source power.
