Lund University, Department of Physics, Synchrotron Radiation

Lund University was founded in 1666 and is repeatedly ranked among the world’s top 100 universities. The University has 40 000 students and 7 600 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

The Faculty of Science conducts research and education within Biology, Astronomy, Physics, Geosciences, Chemistry, Mathematics and Environmental Sciences. The Faculty is organized into nine departments, gathered in the northern campus area. The Faculty has approximately 1500 students, 330 PhD students and 700 employees.

The Department of Physics is with a staff of about 350 scientists and educators one of the largest departments within Lund University. There are seven research divisions and a number of research centra within the department. The research activities at the department cover a broad spectrum of modern physics.

The Division of Synchrotron Radiation Research (http://www.sljus.lu.se) is a part of the Department of Physics and has more than 40 employees. The focus of the research is on experimental studies of electronic, structural, and chemical properties of materials. The Division is developing a new activity focussing on magnetic properties.  At the Division we use and develop a wide range of large facility- and lab-based techniques. We are additionally engaged in the development of the MAX IV Laboratory in the fields of beamlines, experimental stations, techniques for Synchrotron radiation and the accelerator systems. MAX IV (www.maxiv.lu.se/) is a national large-scale research laboratory hosted by Lund University and situated within biking distance from the Department of Physics. It provides scientists from Sweden and the rest of the world with the most brilliant Synchrotron radiation source and instrumentation for research in areas such as materials science, structural biology, chemistry and nanotechnology.

NanoLund (http://www.nano.lu.se), formerly known as the Nanometer Structure Consortium, founded in 1988, supports and coordinates activities within nanoscience and nanotechnology at Lund University. NanoLund is today Sweden’s largest research environment for nanoscience, engaging approximately 250 PhD students and scientists in the faculties of engineering, the natural sciences, and medicine at Lund University. Its vision is to bring together the most creative minds in a world-leading interdisciplinary research environment to help overcome society's grand challenges by pushing the frontiers of nanoscience. NanoLund runs Lund Nano Lab (http://www.nano.lu.se/lundnanolab-2), a state of the art facility for nanofabrication.

Job assignment

This project will use nanofabrication methods to create novel high-resolution X-ray detectors. Detectors convert high-energy X-ray photons into an electrical signal, and are critical in X-ray systems for clinical and industrial applications. Established bulk detectors have relatively large pixels, which limits the resolution in for instance X-ray microscopy. The project aims at reducing the pixel size of X-ray detectors from the current micrometer size to tens of nanometers.

The student will study the interaction of X-rays with nanostructures, with the aim of developing future high-resolution detectors. In particular, nanowires and other nanostructures will be investigated as X-ray detectors. To this end, the project will create 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. Detectors will be made using electron beam lithography, metal evaporation and other nanofabrication tools. 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-rays 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.

The degree does not have to be completed at the time of application.

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:

  • 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.
  • 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.
  • Skills in written and oral communication.
  • Other experience relevant to postgraduate studies, such as professional experience.

Additional assessment criteria are:

  • Experience in semiconductor fabrication techniques such as lithography
  • Experience in semiconductor physics
  • Experience in X-ray sources, X-ray detectors and X-ray imaging
  • Experience in programming
  • Experience in optical and electrical characterization of semiconductors.
  • 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.

Terms of employment

A PhD position is an employment with the main duty to be engaged in PhD studies according to the study plan. The duration of PhD studies is 4 years full time studies. In addition, teaching and other institutional duties normally occur at a level of at most 20% of full time. The position is then extended correspondingly, however not longer than corresponding to 5 years full time employment. PhD positions are subject to special regulations. These can be found in the Swedish Higher Education Ordinance (SFS 1993:100, ch. 5). Only those who are or have been admitted to PhD-studies may be appointed to PhD position.

Application procedure

Apply online! Applications must contain a covering letter in which applicants describe themselves and their particular research interests. Applications must also include a CV, a copy of the applicant’s Master’s thesis (or a summary text if the thesis is not yet completed), contact details of at least two references, copies of grade certificates, and any other documents that the applicant wishes to refer to.
