Welcome!
Our research is linked to optoelectronics, nano-optics, nanothermics, and phase-change materials.

– Optoelectronics. The activity focuses on the bottom-up and solution-processed development of new hybrid materials (perovskites halides, colloidal nanocrystals) and on the study of their structure–property relationships to design advanced optoelectronic devices, in particular solar cells and photodetectors, as well as to explore other emerging device architectures.
– Near-field optics with fluorescent nanoprobes. Our activities concern the study of dielectric and plasmonic nanostructures using a scanning fluorescent probe that detects the near-field. We also study the interactions between fluorescent particles and the local environment.
– Micro and nanothermics. We study thermal properties of compounds and devices using a fluorescent scanning probe microscope. The particle acts as a nanothermometer. By analyzing fluorescence variations we can determine the temperature with a sub-micron lateral resolution.
– Neuromorphic quantum materials and devices. We explore quantum phase-change materials such as vanadium dioxide (VO2) for brain-inspired (neuromorphic) computing. By imaging and controlling their insulator–metal patterns at the micro- and nanoscale, we aim to design energy-efficient artificial neurons and synapses within a single material platform.

We are part of the Laboratoire de Physique et d’Etude des Matériaux (LPEM), a joint lab between the Ecole Supérieure de Physique et de Chimie Industrielle (ESPCI-ParisTech), the Centre National de la Recherche Scientifique (CNRS), and Sorbonne Université.
