This can result from a reduced volume of plasmonic gold, dielectric coating on the gold surface or an increase of electron collision frequency. Using brute-force simulations we identify the contribution of these effects.enTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic EngineeringConference PaperConference Paper
