Silicon nanocrystal-based photonic crystal slabs with broadband and efficient directional light emission

Scientific Reports, 2017
Light extraction from a thin planar layer can be increased by introducing a two-dimensional periodic pattern on its surface. This structure, the so-called photonic crystal (PhC) slab, then not only enhances the extraction efficiency of light but can ...
