Two-dimensional photonic crystals increasing vertical light emission from Si nanocrystal-rich thin layers

Ondič, L; Varga, Marian; Pelant, I; Kromka, A; Hruška, Karel; Elliman, Robert


We have fabricated two-dimensional photonic crystals (PhCs) on the surface of Si nanocrystal-rich SiO2 layers with the goal to maximize the photoluminescence extraction efficiency in the normal direction. The fabricated periodic structures consist of columns ordered into square and hexagonal pattern with lattice constants computed such that the red photoluminescence of Si nanocrystals (SiNCs) could couple to leaky modes of the PhCs and could be efficiently extracted to surrounding air.
