(a) Top view and side view of rotated 2×2×1 BTO–QDs/Ag (R-BTO/Ag) hybrid system, and geometric parameters of BTO–QDs and silver nanowire are both the same as those in Fig. 1(c). (b) Optical absorption of R-BTO/Ag, 2×2×1 BTO–QDs/Ag and silver nanowire. Fourier transformations of the induced charge density distribution of R-BTO/Ag at resonance points of (c) 0.84 eV, (d) 1.72 eV, and (e) 1.41 eV, respectively.
