First-order polarization process as an alternative to antiferroelectricity
Louis Bastogne, Lukas Korosec, Evgenios Stylianidis +6
Antiferroelectrics generate significant interest since their polarization versus electric field (PE) curves show typical double-hysteresis loops appealing for various applications.…

Highly confined epsilon-near-zero- and surface-phonon polaritons in SrTiO3 membranes
Ruijuan Xu, Iris Crassee, Hans A. Bechtel +13
Recent theoretical studies have suggested that transition metal perovskite oxide membranes can enable surface phonon polaritons in the infrared range with low loss and much stronge…

Thermal and electrostatic tuning of surface phonon-polaritons in LaAlO3/SrTiO3 heterostructures
Yixi Zhou, Adrien Waelchli, Margherita Boselli +12
Phonon polaritons are promising for infrared applications due to a strong light-matter coupling and subwavelength energy confinement they offer. Yet, the spectral narrowness of the…
