Direct mapping of the electronic coupling between two self-assembled quantum dots

Dec. 18, 2019 - Guillemin Rodary

Thanks to an advanced technique of scanning tunnelling microscopy and spectroscopy (STM/STS), a team of researchers at C2N was able to observe the electronic coupling of a pair of quantum dots using simultaneous imaging of morphology and electronic density ...

First quantum electron teleportation across a metallic island

Dec. 6, 2019 - Anne Anthore, Frédéric Pierre

A team of researchers at the Centre de nanosciences et de nanotechnologies - C2N (CNRS/Université Paris-Saclay) have observed for the first time the transmission of the quantum state of electrons across a micron-scale metallic island, thanks to a mechanism ...

Nanoporous germanium for cheaper multi-junction solar cells

Nov. 29, 2019 - Gilles Patriarche

News released (in French) by the Institut des Sciences et de l’Ingénierie des Systèmes (INSIS) of CNRS on 25 November 2019 Despite their excellent energy performance, some solar panels are still too expensive to be used widely. ...

A compact optomechanical gigahertz oscillator made of a piezoelectric III-V semiconductor

Nov. 18, 2019 - Rémy Braive

A team of physicists at C2N and Thalès Research and Technology have demonstrated an optomechanical oscillator, based on an ultra-compact bichromatic one-dimensional crystal, able to operate at 3 GHz at room temperature. Oscillators are devices able to produce ...

Mimicking potentials for acoustic-phonons by shaping their propagation through a nanoengineered structure

Oct. 9, 2019 - Daniel Lanzillotti-Kimura

In a theoretical work, a team of researchers at C2N has proposed a novel nanoengineered approach to manipulate the way acoustic-phonons travel through a periodic structure. They have demonstrated that their phononic platform allows studying a variety of potentials ...
