"Three-year PhD position in plasmonic and photo physics: spatially programmed hot-electron generation in plasmonic metasurfaces"

RESEARCHER PROFILE:

PhD/ R1: First stage Researcher

RESEARCH FIELD(S) AND DISCIPLINES:

Physical Sciences, Natural Sciences

JOB /OFFER DESCRIPTION:

We are looking for a curious and motivated PhD student to join our plasmonics and photophysics team and work at the interface of nanophotonics and energy-related applications. Key challenges in solar energy harvesting and photocatalysis stem from limited control of electronic excitations at the nanoscale. Hot electrons in metal nanostructures enable photochemical and optoelectronic processes beyond conventional semiconductors, but practical use is hindered by the lack of spatial control over their generation.

This PhD project will address this by engineering metasurfaces with programmable, spatially localized hot-electron activity. Plasmonic and hybrid nanoantennas arranged in dichroic geometries will be fabricated using scalable lithographic approaches to tailor absorption and hot-electron generation landscapes. Under polarization-controlled illumination, hot-electron activity will be probed via site-selective photocatalysis, photodetection, and localized photopolymerization. In collaboration with material scientists in the group at the CINaM, self-assembled metasurfaces will be studied using the same probing strategies to provide a direct comparison between lithographically fabricated and colloidal metasurfaces. This combined approach will define the limits and opportunities of spatial hot-electron engineering across top-down and bottom-up methods. Moreover, the plasmon-assisted photopolymerization and photocurrent measurements will be performed in collaboration with IM2NP (Institut Matériaux Microélectronique Nanosciences de Provence, Marseille) and ICR (Institut de Chimie Radicalaire, Marseille) institutes.

WHAT WE OFFER:

A fully funded PhD contract for 3 years. The recruited PhD candidate will work in an interdisciplinary and international research environment at the interface of nanophotonics, materials science, and energy-related applications. The project offers access to state-of-the-art nanofabrication, advanced optical characterization facilities, and computational resources, as well as close interaction with experimental and theoretical researchers. The candidate will benefit from strong international collaborations, opportunities for short research stays, training in scientific communication and publishing, and the opportunity to present their work at two international and two national scientific conferences, providing excellent preparation for an academic or industrial research career.

About the group

You will perform this project in the group “Surface Nanostructuring for Energy” under the supervision of Dr. Artur Movsesyan and Dr. Beniamino Sciacca in a highly dynamic and international team. The group has a strong background in synthetic chemistry, surface functionalisation, nanophotonics, nanofabrication, nanoscale photovoltaic devices, and in the characterisation of optical, structural, electrical and chemical properties of materials. The hosting environment is equipped with state-of-the art facilities in nanofabrication and material characterisation.
