英文摘要	To enhance the blue light absorption of silicon, an array of silver nanoparticles(Ag-NPs) was designed so that they create Localized Surface Plasmon Resonance(LSPR) near the surface of silicon(Si). The properties of the enhanced optical absorption of silicon in the blue band were then observed and researched. The blue-light absorption characteristic of silicon in the Ag-NPs/Silicon composite structure were calculated using the Finite-Difference-Time-Domain (FDTD) method. The results indicated that the metallic nanoparticles' extinction capability was related to its geometric parameters and the resonance intensity and peak wavelength can be tuned according to different geometric parameters of Ag-NPs including radius, height and period. At a resonance peak wavelength of 465 nm, the optical absorption of Si in the composite structure (Ag-NPs/Si) rises from 59% to 94% with an array of radius r = 18.5 nm, a height H = 45.0 nm and a period P = 49.0 nm. It concluded that the light absorption gain was 0.57 and photogenerated carriers had a gain factor of 0.53 due to the enhanced light absorption of Si via LSPR in blue band. The results provide a significant reference for the enhancement of the blue-light absorption properties in silicon based on the LSPR effect and the design of a silicon-photodetector with a visible wide spectral resoponse.
