Mind the Gap -- Imaging Buried Interfaces in Twisted Oxide Moirés
Harikrishnan KP, Xin Wei, Chia-Hao Lee +10
The ability to tune electronic structure in twisted stacks of two-dimensional (2D) materials has motivated the exploration of similar moiré physics with twisted oxide membranes. Du…
Electron ptychography reveals a ferroelectricity dominated by anion displacements
Harikrishnan KP, Ruijuan Xu, Kinnary Patel +9
Sodium niobate, a lead-free ferroic material, hosts delicately-balanced, competing order parameters, including ferroelectric states that can be stabilized by epitaxial strain. Here…
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…
