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…
Electrostatic control of quantum phases in KTaO3-based planar constrictions
Jordan T. McCourt, Ethan G. Arnault, Merve Baksi +5
Two-dimensional electron gases (2DEGs) formed at complex oxide interfaces offer a unique platform to engineer quantum nanostructures. However, scalable fabrication of locally addre…
Superconducting vacancy-ordered rock-salt NbO films
Jeong Rae Kim, Sandra Glotzer, Evan Krysko +5
We report molecular beam epitaxy synthesis of vacancy-ordered rocksalt NbO thin films which display superconductivity. A comparative study of substrates identifies AlO (000…
Superconductivity in tin telluride films grown by molecular beam epitaxy
Antonio Gonzalez, Samuel J. Poage, Bernardo Langa +7
The intersection of superconductivity and ferroelectricity hosts a wide range of exotic quantum phenomena. Here, we report on the observation of superconductivity in high-quality t…
Violation of Pauli Limit at KTaO3(110) Interfaces
Samuel J. Poage, Xueshi Gao, Merve Baksi +7
The superconducting order parameter at the KTaO3 interfaces and its dependence on interface orientation remains a subject of debate. The superconductivity at these interfaces exhib…
Surface and Bulk Two-Level System Losses in Lithium Niobate Acoustic Resonators
Rachel G. Gruenke-Freudenstein, Erik Szakiel, Gitanjali P. Multani +7
Lithium niobate (LN) is a promising material for building acoustic resonators used in quantum applications, but its performance is limited by poorly understood material defects cal…
