During recent years the Division of Synchrotron Radiation Research (www.sljus.lu.se) been among the fastest growing parts of the Department of Physics and has now more than 40 employees. The main focus of the research are experimental studies of electronic, structural, and chemical properties of materials, especially of surfaces, interfaces, nanomaterials, free molecules, and clusters. At the division, which closely collaborates with the MAX IV Laboratory (www.maxiv.lu.se) we use and develop a wide range of synchrotron- and laboratory-based techniques, such as x-ray photoelectron spectroscopy/imaging and x-ray diffraction/imaging. We also host Sweden's largest facility for scanning probe microscopy.


Job assignment


The PhD student will use synchrotron-based measurement techniques to perform real-time investigations of catalytic active model systems such as single crystal, metal oxide film, or functionalized graphene surfaces. The key instrument for this work is the new ambient pressure x-ray photoelectron spectroscopy instrument at the HIPPIE beamline at the MAX IV laboratory in Lund. At this instrument it is possible to acquire APXP spectra, polarization-modulation infrared reflection absorption spectroscopy (PM-IRAS), and quadrupole mass spectroscopy simultaneously and at operando conditions. Furthermore, the combination of the intense synchrotron light, the fast electron detector, and the advanced gas mixing system makes time resolved measurements possible. Using this unique experimental setup the planed PhD project is focused on the study of model catalyst surfaces at off-equilibrium conditions established by rapidly oscillating the gas mixture or temperature. In previous and current studies of model catalyst surfaces the goal has been to identify equilibrium and majority phases present while the model catalyst is active, but very little is known about off-equilibrium catalysis which is the central field of this PhD project.


In addition to the work at the HIPPIE beamline surface characterization before and after reactivity measurements will be conducted using other surface sensitive techniques such as scanning tunnelling microscopy (STM) and thermal desorption spectroscopy (TDS). Experimental work at other synchrotron facilities or laboratories around the world is also foreseen in the current PhD project.


The PhD student will work in a multidisciplinary fashion, in which collaboration with both experimentalists and theoreticians is a corner stone of the scientific work. We offer you the opportunity of a broad postgraduate education in a highly stimulating environment. You will have a focus on large-scale research facility-based analysis methods, but you will also have the opportunity to develop skills using other experimental methods and to collaborate with chemists and theoreticians. We expect you to be highly motivated to contribute to the scientific progress in the project. You are a hands-on person and feel comfortable with working both in the lab and with demanding data analysis and interpretation.


The main task for the doctoral student will be to conduct research education which includes work with research but also to master graduate courses.


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 (e.g. materials science or chemistry), orsubstantial 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:


Knowledge and skills relevant to postgraduate studies within the research area, such as a broad and thorough preparation in the natural sciences. 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.Other assessment criteria:


Experience of work with ultrahigh vacuum, x-ray spectroscopy and/or catalysis are considered an advantage. 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, those appointed to doctoral student position may be required to work with educational tasks, research and technical/administrative duties 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, with updates). 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.
