Emerging Phase Transitions and Phenomena in Complex Oxide Membranes

Complex oxides are fascinating materials that exhibit a diverse range of electrical, magnetic, optical, and thermal properties. The advent of freestanding oxide membranes offers exciting opportunities to explore emerging properties in these materials through strain and other external stimuli. In this talk, I will highlight the enormous potential of this new materials platform for enabling and probing emerging phase transitions and phenomena in complex oxides. This includes size-induced ferroelectric transitions in lead-free antiferroelectric membranes and highly confined surface phonon polaritons in strontium titanate membranes.
