Abstract

Localized surface plasmons have been reported for periodic 2D monolayer black phosphorene (BP) nanoribbons in the infrared region. The anisotropic nature of BP causes different plasmonic effects depending on their orientation over select dielectric substrates, leading to tunability and promising future applications in imaging and other detectors. Computational models are used to demonstrate that by tuning the localized plasmonic resonance, as well as the orientation of the BP nanoribbon, it is possible to obtain desired coupled resonance modes and enhanced absorption capabilities. The modes obtained from the absorption spectra span the infrared range and extend our understanding of BP plasmons.
