InGaN/GaN Nanowire Flexible Light Emitting Diodes and Photodetectors

In this paper, we present our recent progress towards flexible nitride nanowire devices: we propose a method to combine high flexibility of polymer films with high quantum efficiency provided by nitride nanowires. The liftoff and transfer procedure allows to assemble free-standing layers of nanowire materials with different bandgaps without any constraint related to lattice-matching or growth condition compatibility. Following this method, we demonstrate blue, green, two-colour and white light emitting diodes as well as p-n photodiodes for integrable UVA sensors.
