Cathodoluminescence spectroscopy of photonic modes in dielectric nanostructures

Control and understanding over the interaction between light and nanostructures can improve light trapping in solar cells. In this project you will use high-energy electrons to excite resonant optical modes in dielectric nanostructures and collect and analyze the spectra and angular distribution of the emitted light in order to gain insight in how the structure interacts with light. The goal is to design the structure such that the excited resonances in the structure interfere destructively in the far field, creating understanding how light is best trapped in the solar cell. You will use numerical simulations, cleanroom nanofabrication, and cathodoluminescence spectroscopy to design and test such resonances in dielectric nanostructures.


About the group

The Photonic Materials group (, led by Prof. Albert Polman, studies light-matter interactions at the nanoscale. The group is composed of an international team of 8-10 PhD students, postdocs and masters students that work in a collaborative atmosphere with many social group activities. Every week we hold group meeting, CL team meeting, and departmental colloquium and poster sessions, in addition to regular journal clubs. We also regularly organize an international group labtour.

Our group is part of AMOLFs Nanophotonics and Light Management in new Photovoltaic Materials research centers that are composed of 8 research groups (50 PhD students and postdocs) that share a state-of-the-art cleanroom for nanofabrication and characterization and many other facilities.


You have a Bachelor’s degree in physics, chemistry or biology and will participate in a Master study during the entire internship period. The internship must be a mandatory part of your curriculum. You have a nationality of an EU member state and/or you are a student at a Netherlands University. Please note: As of January 2021 the UK is no longer an EU member state. You must be available for at least 10 months.

Terms of employment

At the start of the traineeship your trainee plan will be set out, in consultation with your AMOLF supervisor.
