扫描电子显微镜中的量子控制电子波包

Work Activities

In this project, you will explore the interaction between high-energy electrons and intense nanostructured light fields in a scanning electron microscope. During this interaction, electrons can absorb or emit one or more photon energy quanta, placing them into a quantum mechanical superposition state. As a result, the electron-initially a point charge- transforms into a complex wavepacket in space and time. The goal of this project is to investigate the use of optical metasurfaces to control nanoscale light fields, with the aim of shaping the electron energy spectrum and wavepacket profile at will. These shaped wavepackets could enable novel forms of ultrafast quantum-coherent materials spectroscopy. The project involves nanofabrication of metasurfaces, setting up a system to modulate light fields, and measuring the electron energy and light emission spectra and their correlations.

Qualifications

You are currently enrolled in a Master's program in physics, nanophotonics, photonics, materials science, or a related field. You have a nationality of an EU-member state and/or you are a student at a Netherlands University. The internship has to be a mandatory part of your curriculum. We expect you to be available for at least 6 months, although longer is preferable.

Work environment

AMOLF is a part of NWO-I and initiate and performs leading fundamental research on the physics of complex forms of matter, and to create new functional materials, in partnership with academia and industry. The institute is located at Amsterdam Science Park and currently employs about 140 researchers and 80 support employees.

The Photonic Materis group focuses on three main research themes:

• Quantum cathodoluminescence microscopy
• Light management in photovoltaics
• Optical metamaterials

Working conditions

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