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

Chaos generated with a nanoscale magnetic vortex
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
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 …
