Research engineer: focused ion beam milling of plasmonic nanoantennas

The Institut Fresnel is a research state laboratory based in Marseille / France, devoted to research and higher education. Institut Fresnel is seeking to recruit talented, enthusiastic young scientists who are highly motivated to boost their research career in nanophotonics and related technologies.

Motivation

The successful candidate will be part of the ERC Consolidator Grant project “TryptoBoost” carried out at the Institut Fresnel under the supervision of Jérome Wenger. Our group has acquired a wide expertise in the nanoscale control of light fields in plasmonic nanostructures and its application to enhance fluorescence spectroscopy applications focusing on single molecules [1-6]. Our next project aims at efficiently monitoring single proteins using their fluorescence enhanced by optical nanoantennas. The plasmonic optical nanoantennas enable single protein analysis at the physiologically relevant micromolar concentrations thanks to the localization and enhancement of light-matter interactions at the nanoscale.

Job description

To strengthen our multidisciplinary team, we are seeking for a specialist of nanofabrication of plasmonic nanostructures using focused ion beam milling and related methods. The selected candidate will be performing the nanofabrication of our plasmonic antenna structures using our in-house focused ion beam FIB system. He/She will also characterize and further optimize the samples using scanning electron microscopy SEM and optical microscopy and spectroscopy.

The selected candidate will work under the supervision of Jerome Wenger and benefit from direct mentorship to further develop his/her career.

Required qualifications – Eligibility

To apply for the contract, candidates must hold an internationally-recognized PhD degree in Physics or Engineering.

Experience in a scientific project involving nanofabrication (FIB, EBL) and nanophotonics will be highly appreciated.

No restrictions of citizenship apply to the postdoctoral contract.

Terms of employment

The position is intended as full-time (38 hrs / week, 12 months / year) appointment under CNRS contract. The contracts are offered for two years and can be extended for a supplementary period of two years (four years in total).

Application procedure

Suitable candidates are requested to submit:

  • a Curriculum Vitae, including a fully referenced list of publications
  • a presentation letter with declaration of interests and a description of your past achievements (max. 2 pages)
  • contact email of three potential references

Applications should be submitted by email to jerome.wenger@fresnel.fr.

Selection is based on merit and potential, measured in terms of the academic record and   personal achievements.  Proactivity, participation in community activities, and capacity for team-work are also taken into account.  

The call will remain open until positions are filled.
