The role of Rayleigh-Wood anomalies and surface plasmons in optical enhancement for nano-gratings

AA Darweesh, SJ Bauman, DT Debu, JB Herzog - Nanomaterials, 2018 - mdpi.com
We propose and report on the design of a 1-D metallo-dielectric nano-grating on a GaAs
substrate. We numerically study the impact of grating period, slit and wire widths, and …

[图书][B] Optical Enhancement in Periodic Plasmonic Gratings for SERS and Metal-Semiconductor-Metal Photodetectors (MSM-PDs) Applications

AA Darweesh - 2019 - search.proquest.com
This dissertation is aimed to numerically study the effect of plasmonic grating electrodes on
the efficiency of metal-semiconductor-metal photodetectors (MSM PDs) and the sensitivity of …

Effect of incidence and sidewall taper angles on plasmonic metal–semiconductor–metal photodetector enhancements
