Figure 4: Size dependencies for LHE-F of SiNW and numerical fittings to obtain the equations.
From: Exact comprehensive equations for the photon management properties of silicon nanowire

(a) diameter dependency for SiNW with fixed length 0.5 μm; (b) length dependency for SiNW with fixed diameter 80 nm; original data and interpolated surface (rainbow) of the integrated (c) extinction and (d) absorption intensities, where the dash lines denote the optimal SiNW size. Fitted polynomials with R-square are given aside.
