Absorption Improvement and EM Spectroscopy in Photodetector based on Plasmonic Effect by Introducing SiO2 Layer and Ag Nano Particles
We have a light detector structure based on plasmonic effects for maximum light absorption at a wavelength of 820 nm have suggested and the two-stage absorption rate to have increased considerably compared to the previous ones. Firstly, by placing layers of glass between gold and the semiconductor GaAs is Grating and secondly embedding silver nanoparticles in the metal Grating gold. With the implementation of each stage can be seen to increase light absorption in the detector in this structure we proposed for the first time we’ve done it both ways, to intensify the absorption coefficient is 25.83.
