Quantum Nano-Optoelectronics Group: Post-doctoral position in Development and Optical Control of 2D Ferroelectric Materials

ICFO is offering up to two postdoctoral positions to a well-qualified, highly motivated and dynamic young scientists who wish to enhance their scientific career in a friendly and stimulating environment.

The successful candidates will be joining Quantum Nano-Optoelectronics Research Group lead by Prof. Frank Koppens. They will conduct advanced experimental research within the EIC Pathfinder project 2DFERROPLEX, contributing to the development of all-optical neuromorphic components based on two-dimensional ferroelectric heterostructures.

Key responsibilities include:

Development, preparation, and characterization of high-quality 2D ferroelectric materials (e.g. 3R-TMDs, layered ferroelectrics) using exfoliation, stacking, and ultra-clean heterostructure assembly techniques.

Advanced optical and optoelectronic characterization of ferroelectric domains and excitonic properties, including micro-photoluminescence, Raman spectroscopy, SHG, and near-field optical methods.

Investigation of ferroelectric domain structure, dynamics, and switching mechanisms at the nanoscale, including optical manipulation of polarization states.

Design and execution of experiments demonstrating optical control of ferroelectric polarization via exciton population engineering, including nonlinear optical responses relevant for neuromorphic activation functions.

Analysis and interpretation of experimental data in close interaction with theory, modeling, and AI-assisted optimization activities within the consortium.

Reporting and dissemination of the results.

Applicants must hold a PhD degree (or have submitted their thesis by the starting date) in Physics, Materials Science, Nanotechnology, Electrical Engineering, or a closely related field, with a strong background in condensed matter physics, nanophotonics, or 2D materials research.

Candidates should demonstrate:

Proven post-graduate research experience in two-dimensional materials, ferroelectric materials, van der Waals heterostructures, or optoelectronic devices.

Hands-on experience with optical spectroscopy techniques (e.g. photoluminescence, Raman, SHG) and/or nanoscale characterization tools (e.g. AFM, near-field optics, scanning probe methods).

Experience in low-dimensional material fabrication, cleanroom processing, or advanced sample preparation is highly desirable.

Strong capability to independently design experiments, analyze complex datasets, and publish results in high-impact journals.

Ability to work effectively in an interdisciplinary and international research environment.

ICFO is an equal opportunity employer. Candidates are selected exclusively on merit and potential on the basis of submitted application material. No restrictions related to disabilities, citizenship or gender apply to ICFO positions. ICFO abides by the principles of openness, efficiency, transparency, supportiveness, and international comparability as stated in the European Charter for Researchers and the European Code of Conduct for the Recruitment of Researchers.

Salaries for ICFO Postdoctoral positions are assigned by the Selection Committee, based on experience and seniority of the applicant, as well as the assigned tasks and responsibilities within the group. Standard salaries range from a lower level aligned with national Ramon-y-Cajal fellowships to higher levels aligned with Marie Skłodowska-Curie individual fellowships.

The contract is offered for period of 3 years.

Additionally, a family allowance is also available on request and after corresponding approval for people with family charges in the terms described in the corresponding policy.

Suitable candidates are requested to submit:

Presentation letter with a declaration of interest,

Curriculum Vitae, including contact details,

The contact e-mail of two potential referees.

Candidates will be assessed as they apply and the call will remain open until the suitable candidate is identified.

Candidates may contact [email protected] for formal enquiries regarding the application, as well as address scientific enquiries to [email protected].
