Post-doc - Research Positions Thin-film Physics of XUV Optics

The XUV Optics group is embedded in the MESA+ Institute (www.mesaplus.utwente.nl), which is one of the largest nanotechnology research institutes in the world, delivering competitive and successful high-quality research. The institute employs 500 people of which 275 are PhD’s or PostDocs. With its unique NanoLab facilities the institute holds 1250 m2 of cleanroom space and state-of-the-art research equipment.

Job description

Are you interested in conducting advanced thin film physics research on a most exciting application?

We are looking for motivated and skilled post-doctoral researchers to work on the physics of XUV optics. These optics basically consist of optical stacks of films of nanoscale thickness and come in reflective and transmissive types. The physics and chemistry of these thin film systems need to be controlled with atomic precision.

The aim of our research group is to develop the physics solutions for these tasks, such that new applications can be realized. These range from multi-layered optics engineered to show near-theoretical XUV reflectivity, to highly transparent, few tens of nanometer thin membranes which are robust enough to withstand high XUV power levels. The tasks include the fine-tuning of complex optical indices by altering electronic structures, the reduction of layer roughness levels to a tenth of a nanometer, the control of thin film stresses to below a GPa, and the limitation of thermally and chemically induced diffusion processes. These processes require new types of diagnostics with adequate resolution to film thickness and high sensitivity to chemical state.

The XUV Optics Group at Twente has started a new multidisciplinary research programme on these topics. We develop forefront fundamental research, relevant to high tech applications (www.utwente.nl/xuv/). The research will take place in a state-of-the-art thin film laboratory within the MESA+ Institute for Nanotechnology at the University of Twente, in collaboration with various industrial partners.

 Your goal is to develop the key material science required for XUV optical systems based on nanoscale-thin films.

  • This may include new types of membrane structures that combine strength and transparency, using functional layers to meet requirements on mechanical strength, heat dissipation and chemical inertness.
  • It may also include, as an example of another project, the control of materials diffusion and segregation processes across layers and interlayers and advanced surface analysis using low energy ion scattering (LEIS) and X-ray photo-electron spectroscopy (XPS).
  • Or the hybrid analysis of layered textures using a combination of X-ray, electronic and optical analytical instruments, and the technique of depth-tuned fluorescence analysis to identify and localize the materials in the stack of films.

Your profile

  • You have a PhD degree in solid state or surface physics, materials science, physical chemistry or engineering, or a related field.
  • You have evidenced experience in ion scattering, X-ray analysis, or thin film and interface physics.
  • You have affinity with the realization of physical or chemical depositions of nanoscale thin films (MEMS, CMOS or related) and their optical, structural, and mechanical analysis.
  • You are an excellent team player in an enthusiastic group of scientists and engineers working on a common theme.
  • You are creative, like to push boundaries, and are highly motivated to address a major science challenge in thin film physics.
  • You are fluent in English and able to collaborate intensively with industrial and academic parties in regular meetings and work visits.

INFORMATION AND APPLICATION

Your reaction should include an application/motivation letter, emphasizing your specific interest and motivation, a detailed CV, a publication list, contact details of referees, an academic transcript of B.Sc. and M.Sc. education, and a pdf of your PhD thesis. An interview and a scientific presentation will be part of the selection procedure.

For more information about the position, you are encouraged to contact Prof. Fred Bijkerk at f.bijkerk@utwente.nl, +31 53 4892863 or Dr. Eric Louis at e.louis@utwente.nl, +31 53 4894378.

Our offer

You will be appointed on a fulltime position for two years, with possible extension. The university offers a dynamic ecosystem with enthusiastic colleagues in a stimulating scientific environment. The post-doc salary is between €2.972 euro and €4.274 euro gross per month depending on experience and qualifications. The offer further involves: a holiday allowance of 8% of the gross annual salary and a year-end bonus of 8.3%, a solid pension scheme and numerous professional and personal development programmes.

The organization

The University of Twente. We stand for life sciences and technology. High tech and human touch. Education and research that matter. New technology which leads change, innovation and progress in society. The University of Twente is the only campus university of the Netherlands; divided over five faculties we provide more than fifty educational programmes. We have a strong focus on personal development and talented researchers are given scope for carrying out groundbreaking research.

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status or disability status. Because of our diversity values we do particularly support women to apply.

Within the TNW Faculty (Faculty of Science & Technology) of the University of Twente some 700 staff members and 2000 students are involved in training and research on the interface of chemical technology, applied physics and biomedical technology. Fields of application include sustainable energy, process technology and materials science, nanotechnology and technical medicine. Research, which enjoys a high profile both at home and internationally, has been accommodated in the multidisciplinary research institutes: Mesa+ Institute, TechMed Centra and Digital Society Institute. The faculty works together intensively with industrial partners and researchers in the Netherlands and abroad and conducts extensive research for external commissioning parties and funders.
