Description du sujet de thèse

Tip-enhanced photoluminescence of single molecule on thick insulator
The PhD project aims at studying the relationship between charged state and excited states in single and assemblies of molecules. For that, one needs a technic capable of probing the electronic and optical properties of nanostructures with atomic-scale precisions. The project will rely on the use of an Atomic Force Microscope (AFM) operating at low temperature (4K) and under ultra-high vacuum, that will be used to study chromophores on thick insulating layers.The candidate is expected to have a strong background in condensed matter physics, nanoscience, and/or quantum science. Prior experience in scanning tunneling microscopy and/or ultrafast optics would be an asset.

Contexte de travail

IPCMS (“Institute of Physics and Chemistry of Materials of Strasbourg (IPCMS), UMR 7504 CNRS – University of Strasbourg”), is an internationally well-established research and training center in the field of materials and nanoscience. The staff is affiliated to CNRS (INP, INC) and to Unistra (Physics & Engineering, Chemistry, ECPM, Télécom Physique Strasbourg). The laboratory is organized in 3 departments of physics and 2 departments of chemistry with strong interactions, and gather around 200 members.

The candidate will join the STM team within the Surfaces and Interfaces department. The team comprises four CNRS researchers and three engineers, and has an experimental setup including four scanning tunneling microscopes operating at low temperatures, three of which offer optical access. The candidate will work on the newest instrument, which is specifically designed for measurements combining AFM and photoluminescence.

Le poste se situe dans un secteur relevant de la protection du potentiel scientifique et technique (PPST), et nécessite donc, conformément à la réglementation, que votre arrivée soit autorisée par l'autorité compétente du MESR.
