抜粋

A silicon-based infrared photodetector with metal nanostructures has been drawing attention, while lacking sufficient responsivity. We hereby present a silicon-based infrared photodetector furnished with an array of a nano-scale copper plate which induces localized surface plasmon resonance (LSPR). Each plate is placed at the bottom of a nanohole on a silicon substrate. This device possesses two features: electrically-connected copper resonators and backside-illuminating configuration. They lead to efficient photocurrent generation. As LSPR couples with vertically incident light, this structure can be a solution of realizing a silicon-based infrared photodetector that can be adapted to prevalent semiconductor devices.
