PhD Student in the development of antiferroelectric materials (M/F)
Materials with so-called “ferroic” properties play a key role as functional materials in a large variety of devices. In the most common sense, ferroics include essentially the very useful (anti)ferromagnetic, ferroelectric and ferroelastic materials, where the relevant order parameters are respectively magnetization, polarization and elastic strain. Antiferroelectrics are another member of the family that is both less well-known and much less used in devices; they are typically depicted as analogs of antiferromagnetic materials, with switchable sublattices of antiparallel electric polarization. However, the understanding of their phase diagrams and their potential for applications remains in comparison rather shallow.
This PhD work will take place in the Materials Research & Technology department at LIST, within the “Ferroic materials for transducers” research group, which has a strong experience in studies of phase transitions and structure-property relationship of ferroic materials, combining experimental and theoretical work.
The PhD's tasks will be to synthesize various antiferroelectric materials, and characterize their quality, their phase diagrams and their behaviour under application of an electric field.
The work will include:
- Synthesis by the sol-gel method
- Optimization of the growth processes, as well as structural, chemical and electrical measurements using the instruments and advanced characterization platform available in the department (XRD, Raman, XPS, etc.)
- A good part of the work will be devoted to characterization of physical properties under electric field
