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. electron transitions within quantum-confined ... More »

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. This result, obtained within a collaboration between INAC and the University of Basel, opens new ... More »

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. To overcome this problem, we have developed a ... More »

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. Pinpointing the ... More »

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. In view of real ... More »

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. Nanowires made of nitride semiconductors ... More »

Synchrotron nanobeams opens new opportunities to investigate nanostructures with high spatial (sub-100 nm) and temporal (sub-50 ps) resolutions. Thanks to the parallel exploitation of multiple analytical tools (fluorescence, diffraction and  photoluminescence), it is demonstrated how hard ... More »
