Postdoc Balder – MAX IV, Spectroscopy

Lunds universitet, MAX IV, Spectroscopy

Lund University was founded in 1666 and is repeatedly ranked among the world’s top 100 universities. The University has 40 000 students and 7 400 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

MAX IV is a national large-scale research laboratory providing scientists from Sweden and the rest of the world with instruments for research in areas such as materials science, structural biology, chemistry and nanotechnology. Fully developed it will receive more than 2 000 scientists annually. 200 people are currently employed at the MAX IV Laboratory.

The Balder beamline is dedicated to XAS and XES techniques in energy range 2.4-40 keV. The beamline is in commissioning phase at the 3 GeV storage ring at the MAX IV Laboratory and is expected to go into user operation 2019.

Background
Soil organic matter (SOM) stores a large part of the Earth’s carbon. Yet, our understanding of the molecular processes that control the stability and mobility of SOM is limited. This, in turn, limits our ability to predict how SOM will respond to environmental changes. The fate of SOM is influenced by the complex microbial, chemical and physical interactions in soils, which calls for a cross-disciplinary approach to advance this area of science. One area of particular interest is the interactions between Fe and SOM components, and the role of Fe in SOM redox processes.

Tasks
We are now looking for a postdoctoral scholar with a strong scientific background in XAFS and/or XES spectroscopy and a focus on biogeochemistry/environmental science to join our teams. This position is shared between the Balder beamline at MAX IV and the Centre for Environmental and Climate Research, Lund University. Your research will be conducted within the multidisciplinary research environment  “Molecular Interactions Controlling soil Carbon Sequestration – MICCS”, and your primary research tasks will be to investigate the role of Fe in soil carbon decomposition primarily using XAFS and XES spectroscopy. You are expected to develop new sample environments and experimental protocols to target the critical processes. As part of the Balder beamline team you are expected to participate in support to external users, in maintenance and further development of the beamline. You are also expected to promote X-ray spectroscopy to the biogeochemistry/environmental science community.

Qualifications
The successful candidate must have following qualifications:

  • PhD in the area of geochemistry, soil chemistry, biogeochemistry, physical chemistry or related disciplines completed not more than three years before the date of application.
  • Documented knowledge and practical experience in XAFS spectroscopy methodology (data acquisition and analysis).

For more information about the main supervisor of the project, please see: http://www.nano.lu.se/jesper.wallentin

Job assignment

X-rays have a unique ability to investigate samples in their natural state, such as live cells, proteins in solution or electronic devices in operation. Using state of the art optics, X-rays can now be focused to below 100 nm. Such capabilities are available at the NanoMax beamline at the new MAX IV synchrotron in Lund, Sweden (http://www.maxlab.lu.se).

This project will study the interaction of X-rays with semiconductor nanowires. In particular, nanowires will be investigated as X-ray detectors. Nanowires have shown surprisingly strong electrical response to excitation by hard X-rays, which makes them very interesting as future high-resolution X-ray detectors. The project aims at reducing the pixel size of X-ray detectors from the current micrometer size to tens of nm.

To this end, the project will create single nanowire devices in the Lund Nano Lab (http://www.nano.lu.se/facilities/lund-nano-lab-(lnl)/about-lnl), which has world class facilities for nanodevice fabrication. Using electron beam lithography, metal evaporation and other nanofabrication tools, single nanowires will be electrically contacted. The devices will initially be characterized and optimized using electrical and optical methods. Subsequently, the devices will be tested using nanofocused X-ray beams at the Nanomax beamline at the new MAX IV synchrotron, as well as at PETRA-III in Germany, ESRF in France and possibly other international synchrotron facilities.

The project is primarily experimental and will require extensive work in the cleanroom of the Lund Nano Lab. Knowledge and experience of X-ray scintillation is not required; this will form a part of the training as required.

Entry requirements

A formal requirement for doctoral studies in physics is:

  • a university degree on advanced level within a related field, such as a Master’s degree in physics or equivalent, or
  • substantial advanced course work at the Master level, or comparable, including an independent research project.

Furthermore, the acceptance is based on the estimated ability to accomplish postgraduate studies.

Other requirements:

Good knowledge in spoken and written English is a requirement.

Basis of assessment

Selection to postgraduate studies is based on the expected ability to perform well in the studies. The evaluation of the ability to perform well is based primarily on the results of studies at the basic and advanced levels, in particular:

  1. Knowledge and skills relevant to postgraduate studies within the research area, such as a broad and thorough preparation in physics. This can be documented by appended documents.
  2. Estimated ability to work independently and the ability to formulate and solve scientific questions. This ability can be established, for example, based on undergraduate research experiences, a Master’s thesis or in a discussion of scientific problems during a possible interview.
  3. Skills in written and oral communication.
  4. Other experience relevant to postgraduate studies, such as professional experience.

Other assessment criteria:

For the present position, competence in semiconductor physics and related experimental methods are of special value.

Additional assessment criteria are:

  1. Experience in semiconductor fabrication techniques such as lithography
  2. Experience in semiconductor physics
  3. Experience in X-ray sources, X-ray detectors and X-ray imaging
  4. Experience in programming
  5. Experience in optical and electrical characterization of semiconductors.
  6. Experience with novel materials, such perovskites or nanowires.

Important personal qualities are, beside creativity and a curious mind, the ability to work both independently and in a group and experience in the scientific interaction with researchers from other disciplines and in other countries. We consider good cooperation ability, drive and independent work ability as positive personal attributes.
