Plasmonic-Resonant Bowtie Antenna for Carbon Nanotube Photodetectors

Figure 3

(a) The E-field distribution of the resonance frequency (845 nm) of the bowtie antenna with 𝜃=60^∘, and 𝑡=10 nm. The 𝑥−𝑦 axis show the coordinate for simulation. (b) The 𝑡 dependent peak field intensity max(|𝐸|²), blue curve is the simulation values, and red curve is the exponential fit. The inset shows field intensity enhancement |𝐸|² at wavelength of 830 nm.
