Optical Signature of Moiré Superlattices Formed by Twisted SrTiO Membranes
T. A. M. Ragib Shahriar, Fumikazu Murakami, Xing He +11
Moiré superlattices formed at the interfaces of mismatched lattices have attracted significant interest over the past decade due to their large tunability of band parameters and i…
Defect-engineered scaling of lead-free ferroelectrics with ultralow-voltage switching
Reza Ghanbari, Jiayue Wang, Harikrishnan KP +9
Scaling ferroelectrics to nanometer thicknesses remains a central challenge for low-power, nonvolatile electronics, as leakage currents increasingly dominate with reduced dimension…
Deterministic fabrication of large-area, high-crystallinity oxide moire superlattices
Reza Ghanbari, Eli Rodrigues, Young-Hoon Kim +10
Oxide twistronics extends moire engineering beyond van der Waals materials, offering a promising platform for accessing emergent interfacial phenomena arising from the strong coupl…
Low-loss far-infrared surface phonon polaritons in suspended SrTiO3 nanomembranes
Konnor Koons, Hans A. Bechtel, Javier Taboada-Gutiérrez +6
Phonon polaritons (PhPs), excitations arising from the coupling of light with lattice vibrations, enable light confinement and local field enhancement, which is essential for vario…
