The Classical-to-Quantum Crossover in strain-induced ferroelectric transition in SrTiO membranes
Jiarui Li, Yonghun Lee, Yongseong Choi +7
Mechanical strain presents an effective control over symmetry-breaking phase transitions. In quantum paralelectric SrTiO3, strain can induce the ferroelectric transition via modifi…

Tuning exciton emission via ferroelectric polarization at a heterogeneous interface between a monolayer transition metal dichalcogenide and a perovskite oxide membrane
Jaehong Choi, Kevin J. Crust, Lizhong Li +9
We demonstrate the integration of a thin BaTiO (BTO) membrane with monolayer MoSe in a dual gate device that enables in-situ manipulation of the BTO ferroelectric polarizat…

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…
