Molecular Beam Epitaxy of AgTaO3
Tobias Schwaigert, Joshua Maile, Olivia Peek +6
We report the first synthesis of single-crystal AgTaO3 thin films using molecular-beam epitaxy (MBE). High-quality epitaxial AgTaO3 films were grown on both (001)- and (111)-orient…
Above Room Temperature Ferroelectricity in Epitaxially Strained KTaO3
Tobias Schwaigert, Salva Salmani-Rezaie, Sankalpa Hazra +9
Epitaxial strain is a powerful means to engineer emergent phenomena in thin films and heterostructures. Here, we demonstrate that KTaO3, a cubic perovskite in bulk form, can be epi…
Synthesis of epitaxial TaO thin films on AlO by suboxide molecular-beam epitaxy and thermal laser epitaxy
Yorick A. Birkhölzer, Anna S. Park, Noah Schnitzer +28
Tantalum dioxide (TaO2) is a metastable tantalum compound. Here, we report the epitaxial stabilization of TaO2 on Al2O3 (1-102) (r-plane sapphire) substrates using suboxide molecul…
Large phonon-drag thermopower polarity reversal in Ba-doped KTaO3
Mohamed Nawwar, Samuel Poage, Tobias Schwaigert +6
This study reports the observation of phonon-drag thermopower polarity reversal in Ba-doped KTaO3 thin films, mediated by electron-phonon Umklapp scattering. Epitaxial films with d…
Topotactic oxidation of Ruddlesden-Popper nickelates reveals new structural family: oxygen-intercalated layered perovskites
Dan Ferenc Segedin, Jinkwon Kim, Harrison LaBollita +20
Layered perovskites such as the Dion-Jacobson, Ruddlesden-Popper, and Aurivillius families host a wide range of correlated electron phenomena, from high-temperature superconductivi…
Molecular Beam Epitaxy of KTaO
Tobias Schwaigert, Salva Salmani-Razaie, Matthew R. Barone +6
Strain-engineering is a powerful means to tune the polar, structural, and electronic instabilities of incipient ferroelectrics. KTaO3 is near a polar instability and shows anisotro…
Growth of CuFeO Single Crystals by the Optical Floating-Zone Technique
Nora Wolff, Tobias Schwaigert, Dietmar Siche +2
CuFeO single crystals up to 50 mm in length and up to 10 mm in diameter were grown by the optical floating-zone method. Stoichiometric polycrystalline rods with a diameter of 6…
