Controlling carbon nanotube photoluminescence using silicon microring resonators

By depositing carbon nanotubes on ring-shaped micro-resonators, researchers at C2N (CNRS / Université Paris-Sud) managed to control the light emitted by the nanotubes. This technology could be optimized for future applications in optical telecommunications or integrated circuits for microelectronics. This work was published in the journal Nanotechnology.

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 …
