Solid-state materials science (lead by P. Vanek)

We investigate materials with globally or locally broken center of inversion, such as piezoelectric, ferroelectric, antiferroelectric, relaxor or incommensurate dielectrics in form of crystals, ceramics, films as well as complex nanostructures. The team focuses on developing preparation methods, by characterization of structural phase transitions by calorimetric, structural and nonlinear optic methods, and by theoretical modeling of their physical properties.
