Emmanuelle DELEPORTE, alumni of Ecole Normale Supérieure Paris (ENS Paris, 1986 – 1990), received her PhD in Physics from Pierre et Marie Curie University in Paris in 1992. She was assistant professor at the Physics Department of ENS Paris from 1992 to 2002, where she gained strong experience in optical properties of II-VI and III-V inorganic semiconducting heterostructures. In 2002, she moved to Ecole Normale Supérieure Paris-Saclay (ENS Paris-Saclay) as a full professor, where she founded her research team about the optical properties of hybrid halide perovskites.

E Deleporte’s team studies experimentally the linear and non-linear, continuous and time-resolved optical properties of hybrid halide perovskites, for applications such as light-emitting devices and photovoltaics. The main topics addressed are related to low-dimensional excitonic effects, carriers relaxation mechanisms, energy and charge transfers, light–matter interaction in cavities containing hybrid perovksites.

E. Deleporte was the head of the Physics Department of ENS Paris-Saclay from 2006 to 2016. Since 2017, she is the head of the Think Tank “Halide Perovskites” (Groupement de Recherche HPERO) supported by CNRS (Centre National de la Recherche Scientifique).

In 2015 he was awarded a Marie Skłodowska-Curie Individual Fellowship at the Institute of Photonic Sciences (ICFO, Spain). Since 2020 he is Principal Investigator of the Photonic Nanomaterials group at IIT after being awarded an ERC Starting grant. Francesco is a materials scientist with more than 10 years of research experience in optoelectronics.

Current research interests and methodology: Nanomaterials for classical and non-classical light-sources: This research activity focuses on the investigation of synthetic routes to obtain highly luminescent semiconductor colloidal nanocrystals and exploit such material in light-emitting diodes (LEDs). Here, we study how chemical treatments of colloidal nanocrystals can promote enhanced performance in devices, and physico-chemical properties of nanocrystals (e.g. self-assembly and surface chemistry) can be exploited to fabricate optoelectronic devices with innovative architectures. Novel methods and materials for light-emitting diodes: The group applies materials science to optoelectronics by determining which fabrication parameter lead to enhanced performance in LEDs. In order to transition from classical to non-classical light-sources based on colloidal nanocrystals, the group is developing novel methods for controlling the deposition and positioning of an individual nanocrystals in the device. Both “top-down” and “bottom-up” approaches are investigated.

Jennifer A. Hollingsworth is a Los Alamos National Laboratory (LANL) Fellow and Fellow of the American Physical Society, Division of Materials Physics, and The American Association for the Advancement of Science. She currently serves as Councilor for the Amercan Chemical Society Colloid & Surface Chemistry Division. She holds a BA in Chemistry from Grinnell College (Phi Beta Kappa) and a PhD degree in Inorganic Chemistry from Washington University in St. Louis. She joined LANL as a Director’s Postdoctoral Fellow in 1999, becoming a staff scientist in 2001. In 2013, she was awarded a LANL Fellows’ Prize for Research for her discovery and elaboration of non-blinking “giant” quantum dots (gQDs). In her role as staff scientist in the Center for Integrated Nanotechnologies (CINT; http://www.lanl.gov/expertise/profiles/view/jennifer-hollingsworth), a US DOE Nanoscale Science Research Center and User Facility, she endeavors to advance fundamental knowledge of optically active nanomaterials, targeting the elucidation of synthesis-nanostructure-properties correlations toward the rational design of novel functional materials. Her gQD design has been extended to multiple QD and other nanostructure systems, and several are being explored for applications from ultra-stable molecular probes for advanced single-particle tracking to solid-state lighting and single-photon generation. A recent focus of her group is to advance scanning probe nanolithography for precision placement of single nanocrystals into metasurfaces and plasmonic antennas.

Maksym Kovalenko has been a tenure-track Assistant Professor of Inorganic Chemistry at ETH Zurich since July 2011 and Associate professor from January 2017.
