Direct measurement of the lifetime and coherence time of Cu2O Rydberg excitons
Poulab Chakrabarti, Kerwan Morin, Delphine Lagarde +2
Rydberg states of excitons are promising quantum objects to engineer giant nonlinearities in a solid-state system. For this purpose, a deeper understanding of the dynamics of Rydbe…
Using Light to Polarize and Detect Electron Spins in Silicon
Xavier Marie, Delphine Lagarde, Andrea Balocchi +5
Despite decades of research, demonstration of all-optical detection and control of free electron spins in silicon remains elusive. Here, we directly probe the electron spin propert…
Performance of graphene Hall effect sensors: role of bias current, disorder and Fermi velocity
Lionel Petit, Tom Fournier, Géraldine Ballon +5
Graphene Hall effect magnetic field sensors hold great promise for the development of ultra-sensitive magnetometers. Their performance is frequently analysed using the two-channel…
Large-scale characterization of Cu2O monocrystals via Rydberg excitons
Kerwan Morin, Delphine Lagarde, Angélique Gillet +2
Rydberg states of excitons can reach microns in size and require extremely pure crystals. We introduce an experimental method for the rapid and spatially-resolved characterization…
