Optoelectronics of confined Nanomaterials

Scientific activity

The OCN (Infrared Optoelectronics Using Nanocrystals) group at INSP (Institut de la Physique du Globe de Paris / CNRS / Sorbonne University) is dedicated to the design, study, and integration of infrared optoelectronic devices using narrow bandgap nanocrystals as active materials.

Quantum dot synthesis: development of innovative growth methods, particularly for low-bandgap nanocrystals.

Transport and electronic structure studies: electronic characterization via transport measurements (with gate application, temperature dependence, etc.) and spectroscopy (infrared, photoemission) to understand fundamental properties and optimize materials and interfaces.

Quantum sensors operating in the infrared range: production of sensors and SWIR (short-wave infrared) imagers, control of light-matter interaction.

Investigation of light emission: development of LEDs or visible and infrared emission devices, study of optical coupling (cavities, photonic or plasmonic structures).
