Available Positions

1. Topic: Understanding polarity of crystals obtained by symmetry reduction (molecular crystals doped stereo specifically reduces symmetry and develops a set of a very unusual properties).
2. Pre-requisites: common sense (if available) basics knowledge in chemistry or materials science or engineering. Chemical engineering background is also good.
3. Skills to master: growth of organic crystals and their structural characterization. Measurements of pyroelectric, piezoelectric, and elastic properties.
4. Type of work for a M.Sc. project: answering a specific question about the novel the structure-property relations. Trying to make some sense of how they are related and why they do not follow the theory that worked well for 140 years.

1. Novel materials and methods for electromechanical coupling in solids. Piezoelectric thin films. Development of non-classical electrostrictors as ceramics and thin films. Electro-Chemo-X effects (X=mechanical, electrical, magnetic i.e. Solid State Chempotronics) and micro-devices based on these effects. Micro-electromechanical systems (MEMS) based on non-classical electrostrictors: actuators, switches, memory devices, micro-pumps, tunable capacitors and inductors.
2. Pre-requisites: common sense (if available) basics knowledge in either of these fields: materials science/chemical engineering/inorganic chemistry/applied physics. One the fields is enough. The rest can be learnt on the fly
3. Skills to master: microfabrication and MEMS, materials engineering design, basic of electrical characterization (low fields and high fields), structural characterization techniques, basics of device reliability assessment.
4. Type of work for a M.Sc. project: answering a specific question about the novel material/actuation mechanism. Includes: preparation (usually known) and characterization of a specific property correlating it with the composition and preparation method
