Benefits of Cryogenic Growth
- Lower quasiparticle density,
- Reduced noise sources, and improved coherence times
Transmission electron microscopy image, showing the perfect interface of 20 nm-thick aluminium (111) grown on a GaAs (001) substrate at a temperature <100k for more than 3 hours. Results obtained from Epicentre
First Josephson junction achieved in the framework of Epicentre by Sébastien Plissard and his team.
This development and the results presented were carried out as part of the EPICENTRE joint laboratory with LAAS-CNRS Toulouse (a member of Renatech network).
