Based on the Lorenz-Mie light scattering theory, we have calculated the light absorption of single silicon nanowire with Si3N4coating, and compared with pure single silicon nanowire. The calculated result indicates that there exists an enhanced absorption in the Si3N4-coated silicon nanowire and shows a great photocurrent enhancement factor (~70%) for the coaxial NW with the shell thickness of ~70 nm. For a special shell thickness (175 nm) in the Si3N4-coated silicon nanowire forr= 150 nm, the enhancement comes up to ~98.45%.

Examination of the allometric scaling of light absorption (acell) and scattering (bcell) by 28 phytoplankton species showed that light absorption is scaled to the cross-sectional area of the cells (log acell (square micrometres per cell) = −1.06 + 2.32 log d (micrometres)) whereas light scattering is scaled to their volume (log bcell (square micrometres per cell) = −1.09 + 3.45 log d (micrometres)). The scaling of light absorption to the cross-sectional area of algal cells is explained by a decrease in intracellular chlorophyll a concentration as cell size increases, thereby avoiding inefficient light capture by photosynthetic pigments. The scaling of light scattering to cell volume conforms to the general theory for large particles (Mie theory). Light absorption by phytoplankton cells, unlike light scattering, deviates from that of nonliving particles because of the covariation between pigment content and cell size that help prevent self-shading.
