| Figure 1. (a) 3D diagram of the silicon SCs with 60 nm Si3N4 and hexagonally packed α-NaEr0.2Y0.8F4 NSs on the surface; (b) and (c) top view and oblique view of the periodic arrays of α-NaEr0.2Y0.8F4 NSs. The black rectangle of dimension indicates the lattice constant; (d) schematic of planar SCs with Si3N4 layer on the surface and Ag layer on the bottom; and (e) schematic of planar SCs with α-NaEr0.2Y0.8F4 NSs arrays on the surface. |
