Nanophysics and Semiconductors - NPSC

The NPSC group is a joint group between the Institut Néel – CNRS / Université Grenoble Alpes, and the Institute for Nanoscience and Cryogenics of the CEA-Grenoble.

Our activities are related to semiconductor heterostructures using a wide range of materials: nitride, arsenide, II-VI semiconductors. The major fields of research developed in the group are :

  • the growth of semiconductor nanostructures – namely quantum dots, nanowires, quantum wells and their integration with optical microstructures like cavities, photonic nanowires or plasmonic nanoantennas
  • the development of an expertise in structural caracterization of those nanostructures (X-ray, TEM...)
  • the optical study of new physical phenomena resulting from the reduction of the size of these objects. We are especially involved in the manipulation and the detection of individual photons and/or spins.

The studies are carried out with a view to opening up new paths for future applications in spin-electronics, photonics, quantum optics and energy.

Recent research

Strain-mediated coupling in a quantum dot–mechanical oscillator hybrid system

We have realized an hybrid system made of a vibrating wire and a semiconducting quantum dot. The very large coupling between these two subsystems relies on mechanical strain, and is a first step towards the possibility of mapping the quantum properties of a single two-level system made by the quantum dot onto a mechanical oscillator
