Size Dependence of the Directional Scattering Conditions on Semiconductor Nanoparticles

The resonant modes observed in semiconductor nanoparticles and the coherent interaction between them, producing directional light scattering, may be very interesting for CMOS integrated all-optical devices. In these systems, the control over the light scattering should be crucial, as well as the strength of this control. Fabrication parameters such as the size and shape of the nanoparticles and the optical properties of the environment can strongly affect to the emergence of these phenomena. In this letter, we numerically explore the size dependence of the directional scattering conditions of semiconductor nanoparticles. Several semiconductor materials and a large size range have been considered as a reference for further works. An interesting and unexpected linear behavior has been observed.
