Plasmonically Enhanced Amorphous Silicon Photodetector With Internal Gain

Photodetectors made of amorphous materials enable low-cost optical imaging and communications over non-semiconductor platforms. The key challenges are to improve efficiency, sensitivity, and frequency response. Using the localized surface plasmon resonance (LSPR) effect and an efficient carrier multiplication process, cycling excitation process (CEP), the plasmonically enhanced amorphous silicon p...
