~20x Enhancement in Silicon-on-Insulator Photodetector Near ? = 800 nm

The addition of a monolayer of nanoparticles can modify significantly the optical properties of the structure that supports it. We recently offered a practical example of that assertion by using a layer of silver (Ag) nanoparticles to increase by nearly 20 times the optical absorption near wavelength λ = 800 nm of a thin silicon-on-insulator (SOI) photodetector.
