Researchers at INAC-PHELIQS-NPSC have developed new approaches for the detection of ultraviolet/infrared light using single GaN nanowires. Results have led to the demonstration of the first photodetector-in-a-wire based on intersubband transitions, i.e.

Researchers have succeeded in coupling a semiconductor quantum dot to a vibrating wire. The quantum dot is then able to detect the mechanical vibrations of the wire with very high sensitivity.
Several groups have already reported the fabrication of nanotubes, but such structures exhibit usually poor light emission performances. Indeed, the surface states and defects favor the non-radiative recombination processes that quench light emission.

A new class of optoelectronic devices, such as single-photon sources, is based on semiconductor quantum dots (QDs) embedded in a photonic structure. Nowadays, the best QDs are still obtained via a self-assembly process: these emitters are thus randomly located in the structure.
Leti and Inac received EARTO 2016 Innovation Awards for their new 3D LED. Offering a better price/performance ratio, this new technology will be commercialized by Aledia - a Leti spin-off.

It has been shown in recent years that mechanical stress can be used to tune the electronic and optical properties of semiconductor quantum dots. For instance, this approach has been implemented to adjust finely the emission wavelength of quantum dot single photon sources.

We have studied the growth and optical properties of AlGaN nanowires, a potential candidate for future ultraviolet light sources. We have evidenced that such structures behave as a collection of quantum dots due to short-scale composition fluctuations.

Julien Claudon, researcher at the "Nanophysique et semi-conducteurs" lab (CEA-CNRS joint unit) has been awarded the 2014 CNRS bronze medal, distinguishing the first work of a scientist which made him a talent specialist in his field.
Researchers from SP2M demonstrate a novel optical antenna which funnels very efficiently the emission of a semiconductor quantum dot into a Gaussian optical beam.
