PhD-student: Nanophotonics and quantum physics with electrons and light
Work ActivitiesDid you know high-energy electrons can serve as efficient sources of optical excitation of matter? Our group has developed cathodoluminescence microscopy, in which we use 1-30 keV electrons in a scanning electron microscope (SEM) to excite nanomaterials. The oscillating electric field carried by the electron serves as a broadband (0-30 eV) excitation source with 5 nm spatial and 5 fs temporal resolution. This enables us to study excitations and localized modes of plasmons, 2D semiconductors and a wide range of optical metamaterials. We study excitation dynamics through time-resolved spectroscopy, correlative measurements, holography and perform 3D tomography of complex geometries.
In a parallel project, we use high-power laser pulses to induce very strong optical near fields that change the energy spectrum of the electrons in the SEM. This interaction dresses the electrons into a quantum superposition state which creates a way to tailor the spatial and temporal distribution of electron wavepackets at will. The CL microscope is then operated as a quantum instrument with well-prepared initial electron states that may be entangled with materials excitations. This enables studies of optical excitations at attosecond time resolution. The new technique (called PINEM) opens up an entirely new world of electron microscopy applications in integrated optics, nanophotonics, and opto-electronics and will provide detailed insights into fundamental electron-light-matter interactions that have been inaccessible thus far.
We have vacancies for PhD students and postdoc in all of these topics.
QualificationsYou have a degree in physics or related field, and have strong social, organizational and communication skills.
Work environmentAMOLF 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 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.
Working conditions- The working atmosphere at the institute is largely determined by young, enthusiastic, mostly foreign employees. Communication is informal and runs through short lines of communication.
- The position is intended as full-time (40 hours / week, 12 months / year) appointment in the service of the Netherlands Foundation of Scientific Research Institutes (NWO-I) for the duration of four years
- The starting salary is 2.781 Euro's gross per month and a range of employment benefits.
- After successful completion of the PhD research a PhD degree will be granted at a Dutch University.
- Several courses are offered, specially developed for PhD-students.
- AMOLF assists any new foreign PhD-student with housing and visa applications and compensates their transport costs and furnishing expenses.
For further information about the position, please contact Prof. dr. Albert Polman.
