Activité scientifique

The EPS group develops two main research directions. On one side, the group investigates the physics of semiconductors by probing:

  • the spin dynamics in semiconductors and thin magnetic layers
  • the electronic processes in nitride compounds and devices,
  • the transport under mechanical stress in semiconductor nanostructures.

These studies are based on original techniques such as low energy electron spectroscopy, spin polarimetry, polarized luminescence microscopy and local probe microscopies.

On the other side, the QCMX Lab explores the quantum properties of electronic circuits and matter by coupling superconducting circuits to low-dimensional materials. In practice, we perform quantum transport and circuit QED experiments using hybrid Josephson junctions based on ultra-clean carbon nanotubes. These junctions host electronic excitations in the GHz energy range that are called the Andreev bound states, which constitute an unexploited resource to design novel quantum devices.
