WebbBased on this background, we study the effects of the geometry and structural parameters of InGaN nanowires on the optical response properties. We define the cone ratio and fill factor, respectively, and compare the optical absorption characteristics of InGaN nanowires by using the finite difference time domain (FDTD) method.
