碩士 === 國立臺灣大學 === 物理研究所 === 102 === The periodic structure on metal surface has the nature that under illumination, it will cause surface plasmon propagate among the structure. Surface plasmon bears a unique electric field distribution and photonic properties, when the structure is reduced to nanoscale. In this thesis, we will investigate the enhancement due to a hybrid nanostructure consisting of dielectric-embedded metallic grating. It is found that this novel structure possesses Fabry-Pe rot resonance property through a simulation of electric field strength with varying incident angle. By adjusting the grating period, resonance cavity length and different metals, it is possible to control the resonance wavelength and the properties of surface plasmon to obtain a better enhancement of the light emission arising from semiconductor quantum dots.
