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…
Growth and Interface Engineering of Superconducting TiN on Sapphire by Thermal-Laser Epitaxy
Anthony Hyatt, Anand Ithepalli, Eegene Clara Chung +6
Thermal-laser epitaxy (TLE) extends the accessible pressure, temperature, and growth-rate regimes of conventional molecular-beam epitaxy, enabling in situ laser annealing, high-pur…
Strain-Induced Relaxor Multiferroicity at Room Temperature in Hexaferrite BaFe12O19 Thin Films
Yilin Evan Li, Harikrishnan KP, Sankalpa Hazra +19
Multiferroic materials that combine magnetic and electric order at room temperature are rare. Here, we demonstrate strain-induced room-temperature polar order in the ferrimagnetic…
Three-dimensional imaging of oxygen dopant distribution in SrCuO by electron ptychography
Hongbin Yang, Jinkwon Kim, Desheng Ma +3
Oxygen dopants play a critical role in tuning the properties of cuprate superconductors, yet it is challenging to visualize them at the atomic scale. Here, we use multislice electr…
Crystallography of periodic nanotextures in a strained Mott insulator
Benjamin Z. Gregory, Yorick A. Birkhölzer, Noah Schnitzer +9
Here we investigate stripes of alternating structural phases spontaneously forming in epitaxially strained thin films below the metal-insulator transition. Using large-…
Tracking the local order parameter through the Hubbard exciton decoherence time in the Mott-Hubbard insulator LaVO3
Alessandra Milloch, Paolo Franceschini, Pablo Villar-Arribi +9
The prototypical Mott-Hubbard insulator LaVO3 undergoes a structural phase transition accompanied by the onset of spin and orbital ordering below 140 K. By combining ultrafast opti…
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…
