A major loss mechanism in organic light emitting diodes (OLEDs) is the coupling of emitter molecule field to waveguide modes OLED thin film stack. In this work, a disordered 2D array TiO2 nanodisk scatterers integrated into substrate enable efficient extraction from these modes. Fabrication nanodisks based on bottom-up, colloidal lithography technique and subsequent pattern transfer high refrac...

This work validates a posteriori the use of theory developed ca. 40 years ago by Amatore and Savéant for regular arrays electroactive band or disk electrodes. has been profitably used widely applied in more than 900 research papers treatment voltammetric responses nanoelectroactive objects that were necessarily random construction. In this we show competitive diffusion interaction between activ...

Highly efficient subtractive tri-color filters of cyan, magenta, and yellow with enhanced color purity and robustness have been proposed and realized, by exploiting a silicon-aluminum (Si-Al) hybrid-nanodisk (ND) metasurface atop a Si substrate. The aspect ratio of the Si-Al hybrid ND is much lower than that of the conventional Si nanowire, which is disadvantageous due to its fragility and low ...
