A PhD scholarship is now available at the Department of Physics of the Technical University of Denmark (DTU).

The project will use a novel approach of directly measuring heterogeneous nucleation and early stage transient growth kinetics in ferroelectric materials using time-resolved 3D x-ray diffraction microscopy. The candidate will be among the first users of a state-of-the-art hard x-ray microscope at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. Uniquely, the technique provides completely new insight into fundamental phenomena for an important class of materials.

The position is part of a strategic partnership with the Department of Physics at the Norwegian University of Science and Technology (NTNU) in Trondheim. The candidate will make a partial exchange there, where he/she will collaborate closely with project partner Prof. Ragnvald Mathiesen and his group, and have the opportunity benefit from NTNU’s extensive resources and diverse range of relevant expertise.  

Responsibilities and tasks  

  • Optimizing the required instrumentation for dynamic in-situ 3D measurements, in collaboration with instrumentation experts at the ESRF.
  • Making the first high-speed 3D measurements of nucleating and propagating phases and domains in prototypical ferroelectric materials (e.g. ceramics and single crystals)
  • Develop and adapt software to reconstruct quantitative 3D maps from sparse imaging data
  • Correlating this new data with current understanding of ferroelectric and related materials, and disseminating the work in papers and at international conferences.

Qualifications
Candidates should have a master’s degree in physics, materials science or a related discipline. Experience in computer programming is essential. Demonstrated experience in diffraction and microscopy techniques, and their application to ferroelectric materials are desired. 

The successful candidate will be creative, motivated and have good communication skills. In addition, he/she should be willing to travel for experiments at international large-scale facilities, and for the exchange stay at NTNU.   

Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.  

Assessment
The assessment of the applicants will be made by Asst. Prof. Hugh Simons and Prof. Henning Friis Poulsen.  

We offer
We offer an interesting and challenging job in an international environment focusing on education, research, scientific advice and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world.  

Salary and appointment terms
The salary and appointment terms are consistent with the current rules for PhD degree students. The starting date is flexible, but can be no later than September 1st. The period of employment is 3 years.  

Further information
Further information may be obtained from Asst. Prof. Hugh Simons, husimo@fysik.dtu.dk or Prof. Henning Friis Poulsen, hfpo@fysik.dtu.dk.

Application
Please submit your online application no later than 7 May 2017. Applications must be submitted as one pdf file containing all materials to be given consideration. To apply, please open the link "Apply online," fill in the online application form, and attach all your materials in English in one pdf file. The file must include: 

  • A letter motivating the application (cover letter)
  • Curriculum vitae
  • Grade transcripts and BSc/MSc diploma
  • Excel sheet with translation of grades to the Danish grading system (see guidelines and excel spreadsheet here)

Candidates may apply prior to ob­tai­ning their master's degree, but cannot begin before having received it.

All interested candidates irrespective of age, gender, race, disability, religion or ethnic background are encouraged to apply.

The Department of Physics researches physics of fundamental interest and with clear application and innovation potentials. We embrace projects that are curiosity driven and projects that are closely related to strategic agendas in society.
