The fovea centralis is a closely-packed vertical array of inverted-cone photoreceptor cells located in the retina that is responsible for high acuity binocular vision. The cones are operational in well-lit environments and are responsible for trapping the impinging illumination. We present the vertical light-funnel silicon array as a light-trapping… (More)
Supplementary information S1: SEM micrographs of four SiNCs (tilt 70°) and one SiNW (tilt 45°) fabricated by cryogenic RIE with SF6 and O2 chemistry (scale bar is 1µm). Masking is performed with silica spheres (diameter 1µm). Different shapes can be realized by the adjustment of O2 concentration in the plasma that results in a different amount of under… (More)
