… Abstract: A nano-grating structure with a 5nm slit and 15 nm thickness was simulated.
Optical enhancement, which can be harnessed to improve photo-sensing devices such as
photodetectors and biosensors, was calculated for various tapered nanoslits. … This work
studies the impact of tapered nanoslits on the optical enhancement in the GaAs substrate
when the periodicity is less than 410 nm, wire thickness t = 15 nm, and the separation
nanoslit opening at the bottom is g = 5 nm. The …
