Postdoctoral research fellow position: “Attosecond soft-X-ray spectroscopy and diffraction” at the Vrije Universiteit Amsterdam (VU) / Advanced Research Center for Nanolithography (ARCNL)
The High-harmonic generation and EUV science group at ARCNL, Amsterdam, has an opening for a two-year postdoctoral position.
In this project, you will perform experiments to generate soft-X-ray pulses from high-harmonic generation with a high-power, multi-mJ, 50-kHz mid-infrared optical-parametric amplifier, and utilize those pulses for transient soft-X-ray spectroscopy with femtosecond and attosecond temporal resolution on solid-state samples.
Particular topics of interest include charge transfer dynamics in semiconductor samples and junctions, studies of phase transitions in semiconductors under laser-irradiation, and the effects of secondary electron cascades in the photoexcitation process with high-energy photons.
Ultimately, the goal is to connect spectroscopic transient absorption and reflection measurements with scatterometry and coherent diffraction techniques, in order to enable all-optical attosecond imaging with nanometer-spatial resolution and element specificity.
You have (or will receive in near future) a PhD degree in physics, physical chemistry, electrical engineering, or a closely related subject. You enjoy performing experiments and analysis to stepwise build a deeper understanding of complex physical mechanisms. Experience in one or more of the involved topics (high-harmonic generation, ultrafast lasers and optics, vacuum instrumentation, attosecond and femtosecond science, EUV and X-Ray spectroscopy and scattering), in particular experimentally but also theoretically, is required.
Very good verbal and written communications skills (in English) are required.
CONDITIONS OF EMPLOYMENT
A postdoc position is intended as full-time appointment in the service of VU University Amsterdam for the duration of 2 years. The postdoc salary will be in accordance with university regulations for academic personnel, and depending on experience, range from a minimum of € 2,476 gross per month up to a maximum of € 3,908 gross per month (salary scale 10) based on full-time-employment.
Do you come from abroad? We will assist you with visa applications and compensate your transport costs and furnishing expenses. A favorable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants.
You can find information about VU excellent fringe benefits of employment at www.workingatvu.nl like:
- remuneration of 8,3% end-of-year bonus and 8% holiday allowance
- solid pension scheme (ABP);
- a minimum of 29 holidays in case of full-time employment.
High-Harmonic Generation and EUV Science
The high-harmonic generation and EUV science groups develops and utilizes new high-harmonic generation based EUV and soft x-ray sources in the energy range from 10 – 600 eV for spectroscopy and metrology applications. Specific areas of interest are attosecond and femtosecond time-resolved spectroscopy of complex chemical and solid-state dynamics, new strategies for efficient high-harmonic generation, as well as new routes for nanometer-scale imaging of semiconductor structures. Novel types of attosecond and femtosecond transient absorption and reflection spectroscopies, as well as scattering techniques, are developed, and applied to fundamental question with particular relevance to nanolithography.
The group is equipped with Ti:Sa (Titanium:Sapphire) lasers for high-harmonic generation. In addition, a unique 50 kHz, multi-mJ optical-parametric chirped-pulse amplifier system (OPCPA) is close to completion and will be made available exclusively to this project.
The group houses state-of-the-art lab facilities at the Advanced Research Center for Nanolithography (ARCNL). The Advanced Research Center for Nanolithography (ARCNL) focuses on the fundamental physics and chemistry involved in current and future key technologies in nanolithography, primarily for the semiconductor industry. ARCNL is a public-private partnership between the Dutch Research Council (NWO), the University of Amsterdam (UvA), the VU University Amsterdam (VU) and the semiconductor equipment manufacturer ASML. ARCNL is located at the Science Park Amsterdam, The Netherlands, and is currently building up towards a size of approximately 100 scientists and support staff. We offer a dynamic and open environment, and aim to provide the optimum conditions for young scientists to do exciting research leading to high-impact results, which focus on fundamental physics and chemistry challenges, and might also have direct technological relevance.
