PhD student in Coherent X-ray imaging of nanostructures
Lund University, Faculty of Science, Department of Physics
Lund University was founded in 1666 and is regularly ranked as one of the world’s top 100 higher education institutions. The University has 41 000 students and 7 500 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 ten departments, gathered in the northern campus area. The Faculty has approximately 1900 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.
Division of Synchrotron Radiation Researc is a part of Physics and has more than 40 employees. The main focus of the research is experimental studies of electronic, structural and chemical properties of materials. At the division we use and develop a wide range of synchrotron and lab based techniques, such as X-ray photoelectron spectroscopy/imaging and X-ray diffraction/imaging.
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.
MAX IV is the next-generation synchrotron radiation facility, which is currently being commissioned in Lund, Sweden. The MAX IV facility will be the most brilliant synchrotron light source in the world where scientists will be able to explore different materials and substances with better resolution and on shorter time and length scales than previously possible.

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, and modern X-ray imaging methods use advanced mathematics to achieve a spatial resolution far better than the resolution of the optics. This project will develop novel theoretical, computational and experimental methods for X-ray imaging and diffraction of nanostructures. In particular, we will investigate methods that take advantage of the X-ray coherence to improve the spatial and time resolution.
The project will be performed in collaboration with the NanoMax beamline at the new MAX IV synchrotron in Lund. MAX IV is the first fourth-generation synchrotron, generating X-ray beams with a much higher degree of coherence than previously possible. The project will also involve experimental measurements using state of the art nanofocused X-ray beams at PETRA-III in Germany, ESRF in France and possibly other international synchrotron facilities.
The project will develop and implement iterative methods in software, primarily in Matlab or Python, to achieve the highest resolution. Various nanodevices will be investigated, mainly in collaboration with groups in NanoLund. The balance between theory and experiment can be adjusted to the profile and the interests of the PhD student, and may involve theoretical and mathematical studies.
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, theoretical physics, mathematics or equivalent. At a minimum, all applicants must have studied physics at university level.
· 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:
۱٫ Knowledge and skills relevant to postgraduate studies within the research area, such as a broad and thorough preparation in physics, theoretical physics, mathematics or equivalent. This can be documented by appended documents.
۲٫ 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.
۳٫ Skills in written and oral communication.
۴٫ Other experience relevant to postgraduate studies, such as professional experience.
Other assessment criteria:
For the present position, interest and competence in computational methods in physics and mathematics, including software and algorithm development, is of special value. Valuable, but not absolutely necessary, competencies include X-ray diffraction and imaging, X-ray physics, synchrotron radiation, electromagnetic field theory, and semiconductor physics.
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.
Remarks
We ask companies dealing with advertising job openings and staffing companies to refrain from seeking contact with us since we are bound by contracts in the governmental system.
