Polarized Light-Sensitive, Monolayer MoS2 Plasmonic Phototransistors

The text highlights the significance of polarized light detection in quantum communication. It introduces polarization-sensitive phototransistors made from MoS2 and Au nanorod arrays, optimized through FDTD calculations. These devices exhibit strong linear polarization selectivity at 660 nm, with a 90.5% polarization ratio. The study suggests exploring efficient polarized-light phototransistors using the proposed nanostructure and discusses potential applications of ultrathin phototransistors with high polarization sensitivity.
