About the position

Society is undergoing an energy revolution, decisively shifting away from fossil fuels. While much of the focus is on batteries, thermal energy storage will play a major role as complimentary energy storage technology. In addition, the materials used for the electronic components in devices such as capacitors, needs to be evolved to enable recycling and circular economies.

Ionic plastic crystals are supramolecular materials made from small globular organic and inorganic molecular ions. Their rare combination of long-range crystal structure and local molecular orientational freedom enables properties like piezoelectricity and ferroelectricity, and high entropy phase transitions. It is this unique set of properties that makes them extremely interesting for thermal energy storage, caloric cooling devices, transducers, actuators and sensors – all essential components for our energy future.

We have a vacancy for an enthusiastic PhD candidate in ionic plastic crystals for thermal energy storage and novel electronics. The position is at the Functional Materials and Materials Chemistry (FACET) Research group, in the Department of Materials Science and Engineering, NTNU Norwegian University for Science and Technology.

This academic position will provide the opportunity for the candidate to complete a doctoral education program and obtain a PhD from NTNU, while undertaking professional development activities within the broad fields of research and materials science.

This research project will explore the landscape of ionic plastic crystal chemistry and engineering, with particular focus on developing sound methodologies for modifying the functional properties and the thermodynamic characteristics of the phase transitions. As a PhD candidate you will work on the novel area of compositional engineering in ionic plastic crystals and actively contribute to this growing field of research.

The PhD candidate will pursue experimentally based materials science where they will develop new compositions, design synthesis methodology, and perform detailed structural, thermodynamic and electrical property characterization.

Candidates will be required to perform all sample synthesis themselves in the chemistry laboratory, using mostly wet chemical approaches to crystallite precipitation. This will be followed by detailed analysis with X-ray diffraction and total scatter experiments, both ex situ and in situ as a function of temperature and electric field, performed in the lab and at international user-based synchrotron radiation facilities. Complimentary studies with Raman and Infrared spectroscopy will also be used to help decode the local structure. The use of differential scanning calorimetry will be an essential tool mapping thermodynamic changes across the phase transitions in the different materials. Finally impedance spectroscopy and additional high field leakage current and ferroelectric switching measurements will be employed to characterize additional functional properties as a function of composition. The Candidate will therefore develop a range of skills that will make them a highly accomplished supramolecular chemist as well as an expert in structural and thermodynamic characterization.

Duties of the position

  • The Candidate will be required to plan and carry out independent scientific inquiries into the synthesis-structure-property relationship of ionic plastic crystals.
  • The candidate will collect, analyse, and report thorough data sets pertaining to materials structure and properties using a wide variety of experimental techniques.
  • The candite will work extensively on oral, written, and visual communication of science and will be expected to represent FACET by presenting their research at international conferences.
  • The candidate will be encouraged to contribute to the scientific and learning environment at NTNU through participation in laboratory or equipment management, teaching activities and organisation of group social events.
  • The candidate will be required to mentor master students in the laboratory and assist in the planning and undertaking of the research activities of junior scientists (undergraduates).

Required selection criteria

  • You must have a professionally relevant background in chemistry, materials science or nanotechnology.
  • Your education must correspond to a five-year Norwegian degree program, where 120 credits are obtained at master's level.
  • You must have a strong academic background from your previous studies and an average grade from the master's degree program, or equivalent education, which is equal to B or better compared with NTNU's grading scale. If you do not have letter grades from previous studies, you must have an equally good academic basis. If you have a weaker grade background, you may be assessed if you can document that you are particularly suitable for a PhD education.
  • You must meet the requirements for admission to the faculty's doctoral program 
  • You must have good written and oral English language and communication skills.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for appointment as PhD, post doctor and research assistant  

Preferred selection criteria

  • A candidate that is interested in moving outside of Norway for an extended research visit of 3 to 6 months with a focus on strengthening the international scientific network of the research team.
  • A candidate with knowledge of crystal growth methods or hybrid supramolecular material synthesis will be preferred.
  • Prior experience with organic or inorganic materials synthesis, and/or materials structural characterization techniques is highly desirable.
  • Prior knowledge in organic or inorganic chemistry will be highly advantageous.
  • Candidates showing a desire to learn Norweigian or with Scandinavian language skills will be considered a plus.
  • Candidates with an interest in teaching or taking wider responsibilities within the laboratories are also desired.

Personal characteristics

In the evaluation of which candidate is best qualified for the PhD position, emphasis will be placed on education, experience and personal suitability. The candidate should:

  • Be comfortable working independently to solve complex problems and take responsibility for their own progress.
  • Be a strong communicator, able to share ideas, experiences and information in formal and informal settings.
  • Be a team player, able to see the value of contributing to the team around them as well as working for personal pursuits.
  • Be able to build meaningful professional relationships in the workplace.
  • Foster mutual respect among colleagues, both at NTNU and in international work environments.
  • Be someone with many varied interests, passions, and personal pursuits outside of work. FACET prides itself on promoting balance and diversity in life, and an individual who can contribute to the knowledge of the group in all aspects of life is highly desired.
