Are you a highly motivated physicist interested in a PhD project at the intersection between nanophotonics and 2D material science? The 2D Nanophotonics group within the Institute of Physics has an open position for the project “Excitonic 2D metasurfaces for active multifunctional flat optics”. The aim is to employ exciton resonances in monolayer 2D semiconductors to actively tune the optical response of metasurfaces.

Optical metasurfaces offer ultra-flat and compact alternatives to conventional bulky optical elements like mirrors, lenses, and prisms. By accurate engineering of the resonant light-matter interaction of arrays of nanostructures, light can be scattered in a controlled fashion to perform an optical function. While such optical metasurfaces are nowadays highly efficient and well established, their optical function is typically static.

In this project you will study the strong light-matter interactions of stable excitons in monolayer 2D semiconductor material and couple these materials to resonant metasurfaces. Using their combination, you

will investigate the unique properties of these 2D quantum materials and use them to develop multifunctional and atomically thin optical elements with an electrically tunable optical function.

You will be joining an exciting team of researchers with a strong emphasis on collaboration. We expect you to be an active member of the research group and work

?

You will perform fundamental research on the understanding and use of monolayer 2D van der Waals materials in atomically thin optical metasurfaces.

You will:

• fabricate optical metasurfaces and nanoscale devices in the cleanroom of the AMOLF NanoLab Amsterdam (https://amolf.nl/nanolab);
• design and perform high-sensitivity optical and electronic experiments at cryogenic temperatures;
• develop theory and computer simulations to support the experiments;
• present your results in international workshops and conferences;
• collaborate with other members of the research group, other groups within the Quantum Materials cluster, and (international) collaborators;
• take part in the teaching efforts of the group, including supervision of bachelor and master students.

You have:

• a creative, curious and driven nature;
• a Master’s degree in physics;
• an eagerness to learn new techniques and to combine numerical simulations, theory and experiments;
• excellent written and oral communication skills in English.

You are:

• able to work both independently and collaboratively.

Other skills, experiences, and documents that would benefit your application:

• previous experience in an optics lab or cleanroom fabrication;
• demonstrated experience with programming and modelling software (matlab, python, Comsol, Lumerical);

scientific publications.

A temporary contract for 38 hours per week for the duration of 4 years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years). This should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students.

The gross monthly salary, based on 38 hours per week and dependent on relevant experience, ranges between € 2,541 to € 3,247 (scale P). This does not include 8% holiday allowance and 8,3% year-end allowance. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. The Collective Labour Agreement of Universities of the Netherlands is applicable.

Besides the salary and a vibrant and challenging environment at Science Park we offer you multiple fringe benefits:

• 232 holiday hours per year (based on fulltime) and extra holidays between Christmas and 1 January;
• multiple courses to follow from our Teaching and Learning Centre;
• a complete educational program for PhD students;
• multiple courses on topics such as leadership for academic staff;
• multiple courses on topics such as time management, handling stress and an online learning platform with 100+ different courses;
• 7 weeks birth leave (partner leave) with 100% salary;
• partly paid parental leave;
• the possibility to set up a workplace at home;
• a pension at ABP for which UvA pays two third part of the contribution;
• the possibility to follow courses to learn Dutch;
• help with housing for a studio or small apartment when you’re moving from abroad.

Faculty of Science

This PhD project will be carried out in the 2D Nanophotonics lab headed by Dr. Jorik van de Groep within the Van der Waals-Zeeman Institute (WZI), the experimental division of the Institute of Physics of the University of Amsterdam. Our laboratory focusses on photonic metasurfaces with 2D materials and benefits from an exceptional scientific environment in hard condensed matter, nanophotonics, and materials science. The Institute of Physics is part of the Faculty of Science.

The Faculty of Science has a student body of around 7,000, as well as 1,600 members of staff working in education, research or support services. Researchers and students at the Faculty of Science are fascinated by every aspect of how the world works, be it elementary particles, the birth of the universe or the functioning of the brain.
