Flexible nitride nanowires light emitting diodes

Presently, flexible light sources mainly use organic materials integrated on lightweight and flexible plastic substrates. However, organic LEDs present a much lower luminance and a shorter lifetime in comparison to the LEDs based on inorganic nitride semiconductors. The inorganic semiconductor devices in their bulk form are mechanically rigid. Polymer-embedded nanowires (NWs) offer an elegant solution to create flexible optoelectronic devices, which combine the high efficiency and the long lifetime …
