PhD fellowships LIGHTinPARIS - ELIXIR2 Project on Time-Resolved Stark Spectroscopy, Paris, France(Deadline:23.02.2026)

There are 19 PhD fellowships on offer among 35 PhD thesis projects to choose from:
Among the possible PhD projects, we are very pleased to highlight our PhD project at the LuMIn laboratory (University Paris-Saclay, France):

ELIXIR2: Electrically tuned Indirect eXcitons in In-plane and out-of-plane 2D semiconductoR hetero-nanostructuRes

This project aims to use time-resolved optical Stark spectroscopy to investigate the dynamics of exciton recombination and dissociation in original assemblies and heterostructures of two-dimensional (2D) nanostructures. The goal is to tune the energy and coupling of the excitonic states in strongly confined colloidal quantum wells (nanoplatelets), with the external electric fields.The exciton binding energy will be modified while playing on the spatial overlap (and extent) of the electron and hole wavefunctions (charge transfer character). Dynamics of exciton recombination & dissociation will be probed by photoluminescence using a picosecond streak camera and charge transfer will be scrutinized by femtosecond transient absorption spectroscopy. An important feedback between these measurements and the samples developed at ILM Lyon will be essential to obtain high quality interfaces and composition tunability.
