First ultra-low threshold continuous-wave lasing in Germanium-Tin

March 18, 2020 - Moustafa El Kurdi

Transistors in computer chips work electrically, but the data can be transmitted more quickly with light. Researchers have therefore been looking for a way to integrate a laser directly into silicon chips for a long time. Researchers at C2N, ...

Teleportation of a quantum state across a metallic island

Feb. 18, 2020 - Anne Anthore, Frédéric Pierre

News released (in French) by the Institut de Physique (INP) of CNRS on 18 February 2020 A team of physicists at C2N have observed for the first time the transmission of the quantum state of an electron ...

Chaos generated with a nanoscale magnetic vortex

Feb. 4, 2020 - Joo-Von Kim

Magnetic vortices are nanoscale whirls that gyrate like spinning tops, tracing out paths in a clockwise or counter-clockwise manner in nanometre-thick materials. Under certain conditions, this sense of gyration can flip repeatedly, resulting in complex patterns of behaviour. Now, ...

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 ...

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. ...
