(a) Maximum values of the particle equivalent radius under EA conditions (1) for Ag particles in GaAs medium. (b) Coordinate system. Light impinges on the particle with its electric field along . The origin is at the particle center. (c) Preferential position for inclusion of MNPs in the plane of the QDs (represented as pyramids).
Spheroid aspect ratios that maximize the polarizability for coated and uncoated Ag MNPs in GaAs medium.
Scattered potential , in units of , at the particle surface ( or ) for the SPP shapes in Fig. 2. The inset shows the value of this quantity at .
Absorption enhancement for spheroids optimally shaped for 0.3 and 1 eV. The curves for the 0.3 eV case are multiplied by 10 for better visualization. The inset is a polar plot of the scattered potential angular distribution at the uncoated MNP surface in the plane, normalized by its maximum at 90°, for the 0.3 and 1 eV shapes.
