摘要
The present disclosure explores and fabricates coupled plasmonic nanoparticles of gold (Au), silver (Ag), or aluminum (Al) onto nanorods or nanowires of zinc telluride (ZnTe), silicon (Si), germanium (Ge), or other semiconductor materials. Full-wave simulation is performed to obtain an optimum design for maximum light absorption. The nanorods, after being coated with a shell to form a p-n junction, or being imparted with a radial junction, are of interest for enhanced light harvesting in solar cells, for example. The fabrication method of such arrays is described. Modeling of the spectral properties using equivalent circuit theory is implemented to predict fabrication results and provide an intuitive approach regarding the design of these optical metamaterials with predetermined properties.
