Figure 2: Size dependencies for RW and numerical fitting to obtain the equation at Main peak.
From: Exact comprehensive equations for the photon management properties of silicon nanowire

(a) Diameter decency of RW for SiNW with fixed length 0.5 μm. (b) length decency of RW for SiNW with fixed diameter 80 nm. (c) The original data (black spheres) and fitted surface (mapped by rainbow) of RW at Main peak, where the 3D view and the d-z, l-z side views are given. The fitted polynomial with R-square is provided aside.
