Ferroelectric Materials


In recent years, ferroelectric materials and thin films have attracted much attention and exhibited potential in many important applications such as dynamic random access memories (DRAMS), non-volatile ferroelectric random access memories, actuators, infrared sensors, etc. Our scientific focus is on the ferroelectric and piezoelectric properties of perovskite oxides and on transition-metal oxides. Experiments will be complemented by atomic-level computer simulations focused on elucidating the relationship between structure and ferroelectric properties in perovskites. The project is based on the premise that comprehensive and fundamental materials modeling validated by selected experiments can be used as an engineering tool for the development of new materials and devices.
