Quantum Dots at Ecole Polytechnique

Assistant Professor, Ecole Polytechnique

Chemistry Department & Physics Department

Hi! I am Clément Livache. I recently joined Ecole Polytechnique and Institut Polytechnique de Paris to develop new activities around semiconductor nanocrystal chemistry, optoelectronics and spectroscopy.

I'm using ultrafast spectroscopy to probe optical and electrical properties of nanoscale semiconductor particles, with applications in energy production, advanced light sources and quantum technologies.

I used to work on quantum dot lasing and advanced spectroscopy in Dr. Klimov's group at Los Alamos National Laboratory, and before that with infrared quantum dots for photodetection at ESPCI Paris and Sorbonne University.

News

September 2025 - I was awarded a 'Young Researcher' JCJC funding from French ANR, for the project 'MetaQD'! The project will start in 2026.

July 2025 - We got internal funding from the interdisciplinary center on materials (M4S) at Ecole polytechnique and IP Paris, that will allow us to buy our ultrafast laser source.

June 2025 - The group participated to the INO Workshop on Infrared Nanocrystals and Optoelectronics organized by Emmanuel Lhuillier and Philippe Guyot-Sionnest at the University of Chicago antenna in downtown Paris. It was great to see how much the field of IR QD photodetection exploded in the past 10 years!
