Postdoc: Optical methods for operando investigation in liquid reactors

Work Activities
The 3DPV group at NWO-Institute AMOLF is looking for a Postdoc candidate on operando characterisation inside a novel plasmonic-based photo-reactor. The project is part of the European ReaCtor consortium, which aims at designing and fabricating a novel micro reactor for sustainable flow chemistry. The consortium combines expertise in optical fiber design and fabrication (Institute of Quantum Optics at Leibniz University Hannover in Germany and Institute of Microelectronics and Photonics in Poland), laser structuring of glass materials (Light-Matter interactions and Extreme-Applications Photonics Lab at University of La Laguna on Tenerife in Spain) and flow chemistry (Noël research group at the University of Amsterdam).

This PD project contributes to the novel micro reactor by investigating the effect of plasmonic metal nanoparticles in enhancing photocatalysis inside optical fiber reactors. Different operando techniques will be pursued to monitor the chemical reactions in space and time, including scanning probe and spectroscopic (i.e. fluorescence and Raman). The goal is to probe the reaction kinetics from the single particle to the ensamble, and determine the ideal plasmonic particle density inside the reactor. In doing so, you will contribute to a novel type of light-driven chemical reactor, which will significantly reduce the energy consumption of catalytic processes in combination with an enormous scale-up potential.

This project will be in close collaboration with the other consortium partners, including consortium researchers at Dr. Albercht’s group at AMOLF and Prof. Noël’s group at the UvA, and you will be part of all consortium activities such as symposia, workshops, and mutual visits.

Postdoc: Investigating the electrical double layer

Work Activities
This is a postdoc position for 2+1 year to experimentally develop the in-situ and operando characterization of metal electrodes.

One of the largest challenges in achieving the energy transition is the conversion and storage of sustainable energy in energy-rich compounds such as hydrogen, hydrocarbons or alcohols produced from water and CO2. The key limiting factor in making these reactions more efficient is the lack of detailed understanding of how these reactions proceed on the nanoscale. In particular, detailed knowledge of the hydrogen-bond structure and molecular dynamics in the interfacial region near the electrode surface is missing. In this project we will combine advanced nonlinear optical femtosecond vibrational spectroscopy with scanning probe microscopy to investigate the water structure on the molecular scale near an operating electrode surface. We will also use these advanced techniques to investigate the dynamic distribution of ions and reactants in the region near the electrode surface. With these studies we will obtain novel insights in the structure of the electrical double layer near a biased electrode surface, which will be of great value in optimizing electrochemical reactions for the conversion and storage of sustainable energy.

This is a joined position between two research groups at AMOLF, the Ultrafast Spectroscopy and the 3DPhotovoltaics groups. You will be supervised by Prof. Bakker and Prof. Alarcon-Llado and will closely collaborate with the PhD students, technicians and other post-docs of both research groups. Both groups are embedded in the Sustainable Materials theme and ChemSpec center of expertise at AMOLF, which offer a highly stimulating and collaborative atmosphere

Qualifications
We are looking for an enthusiastic researcher with a PhD in experimental physics or physical chemistry.

We look for someone with experimental expirience in at least one of the following areas:

  • solid-water interface investigation at the molecular level
  • in-situ/operando atomic force microscopy
  • ultrafast spectroscopy

Good verbal and written communication skills in English are required

PhD position: Droplet deformation by laser impact for EUV lithography

Work Activities
The EUV-emitting laser-produced plasmas are generated from tin targets carefully shaped (hydrodynamically deformed) by a series of laser “pre-pulses”. The ability to shape & control these tin targets is critical for efficient generation of EUV light for current and future light sources. Such abilities will originate from understanding the driving physical processes.

You will join a team of several PhD students and postdocs and have as an objective to design & execute experiments to understand the fluid dynamic deformation, fragmentation, and vaporization of laser-impacted thin liquid tin targets: what really happens when a laser pulse hits a tin droplet? New fluid dynamics understanding will lead to new capabilities for laser-tailoring targets. These new capabilities will allow target tailoring to optimally couple to laser light to produce hot-and-dense plasma. You (and the rest of the team) will be responsible for the setup, execution, analysis, and interpretation of the experiments.

Advanced semiconductor devices are produced using extreme ultraviolet (EUV) light at just 13.5nm wavelength. The recent revolutionary introduction of EUV lithography (EUVL) was the culmination of several decades of collaborative work between industry and science – a Project Apollo of the digital age. EUVL is powered by light that is produced in the interaction of high-energy CO2-gas laser pulses with molten tin microdroplets. The use of such lasers leads to low overall efficiency in converting electrical power to useful EUV light. Replacing gas lasers with much more efficient solid-state lasers may significantly improve efficiency, as well as output power. It is currently however unclear what laser wavelength, and what plasma ‘recipe’ should be used. This is because we lack understanding of the underlying complex physics. The goal of project MOORELIGHT is to deliver the missing insight.

Qualifications
You have (or soon will have) a MSc physics or applied physics. Knowledge about fluid mechanics and/or experimental laser physics and/or (laser) spectroscopy is advantageous. Programming skills (Python) are welcomed. Good verbal and written communication skills (in English) are required.

Work environment
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 associate partner the University of Groningen (UG), and the semiconductor equipment manufacturer ASML. ARCNL is located at the Amsterdam Science Park, The Netherlands, and has a size of approximately 100 scientists and support staff. See also www.arcnl.nl

The research activities of the EUV Plasma Processes group aim at the atomic- and molecular-level understanding of the fundamental dynamics in the operation of contemporary and future plasma-based sources of extreme-ultraviolet (EUV) light for nanolithography.

PhD Position: The stochastic thermodynamics of nanomechanical computers

Work Activities
Scientific background – The energy consumption of computers is a significant scientific and societal problem: Information technology is already responsible for more CO2 emissions than the airline industry. At the fundamental level, the energy cost of a computation is dictated by the laws of thermodynamics: computations must evolve in time in a pre-defined direction – we want our codes to run from the beginning to the end and not in reverse! However, in equilibrium, processes are equally likely to run forward than backward. Establishing an arrow of time (a preferential direction of evolution) requires consuming free energy. The problem of quantifying the energy cost of computers is the domain of stochastic thermodynamics, a sub-field of statistical physics focused on small systems far from equilibrium – as computations are inherently out-of-equilibrium and involve few degrees of freedom (bits).

Key challenge and approach – Experimentally probing the energy limits of computers is challenging because it requires components (logic gates, memories) that can be activated with very small energies, and that have low power losses (such as Joule heating). We plan to tackle this challenge by building (nano) mechanical computers, processing information using very small structures that can bend under tiny forces (encoding a one or a zero depending on the direction of bending), that consume an extraordinarily small amount of energy in the process. We will actuate the nanostructures using optical forces, and measure them using custom, on-chip optical interferometers to quantify the energy consumption.

Key tasks: The Ph.D. position will be primarily experimental. The student will be tasked with fabricating nanomechanical bits and logic gates (in a cleanroom) and experimentally studying their evolution (using photonic characterization tools). Occasional numerical simulations with existing in-house codes will be conducted to help interpret and contextualize the results.

Qualifications
What are we looking for: We are looking for an experimentally-minded student with a MSc degree in physics or engineering. Experience in cleanroom nanofabrication, optomechanics or stochastic thermodynamics is a plus but not required. Perseverance and willingness to take on challenging experiments is a must.

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. www.amolf.nl

What we offer: We are a diverse and international research group, with a supportive and collaborative atmosphere, working on the growing field of information processing in physical systems. The group is hosted in a vibrant department focused on information processing across diverse platforms (photonics, mechanics, biology) with possibility to interact with other leading theoretical and experimental groups. Our institute is equipped with a state of the art, on-site cleanroom (including electron microscopes, electron beam lithography, Nanoscribe, FIB, etching and layer deposition equipment). The Ph.D. includes funding to attend several international conferences. This research, at the forefront of statistical physics, nanotechnology and physical computing, is relevant to fundamental physics as well as to applications given the exponential growth in the energy costs of artificial intelligence.

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.
