Breaking symmetry to create a parallel-plate varactor dielectric with unparalleled microwave performance
Florian Bergmann, Matthew R. Barone, Zishen Tian +24
Voltage-tunable capacitors (varactors) are key to microwave circuits. Tunable dielectric varactors outperform competing technologies in almost every relevant metric but usually suf…
Colossal Cryogenic Electro-Optic Response Through Metastability in Strained BaTiO Thin Films
Albert Suceava, Sankalpa Hazra, Aiden Ross +14
The search for thin film electro-optic (EO) materials that can retain superior performance under cryogenic conditions has become critical for quantum computing. Barium titanate thi…
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…
Low-energy domain wall racetracks with multiferroic topologies
Arundhati Ghosal, Alexander Qualls, Yousra Nahas +13
Conventional racetrack memories move information by pushing magnetic domain walls or other spin textures with spin-polarized currents, but the accompanying Joule heating inflates t…
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…
Picosecond expansion in LaAlO3 resonantly driven by infrared-active phonons
Jakob Gollwitzer, Jeffrey Z. Kaaret, Y. Eren Suyolcu +19
We investigate the ultrafast structural dynamics of LaAlO3 thin films driven by short mid-infrared laser pulses at 20 THz. Time-resolved X-ray diffraction reveals an immediate latt…
Morphogenesis of Spin Cycloids in a Non-collinear Antiferromagnet
Shashank Kumar Ojha, Pratap Pal, Sergei Prokhorenko +11
Pattern formation in spin systems with continuous-rotational symmetry (CRS) provides a powerful platform to study emergent complex magnetic phases and topological defects in conden…
In situ etching of \b{eta}-Ga2O3 using tert-butyl chloride in an MOCVD system
Cameron A. Gorsak, Henry J. Bowman, Katie R. Gann +9
In this study, we investigate in situ etching of \b{eta}-Ga2O3 in a metal-organic chemical vapor deposition (MOCVD) system using tert-Butyl chloride (TBCl). We report the successfu…
Spontaneous supercrystal formation during a strain-engineered metal-insulator transition
O. Yu. Gorobtsov, L. Miao, Z. Shao +13
Mott metal-insulator transitions possess electronic, magnetic, and structural degrees of freedom promising next generation energy-efficient electronics. We report a previously unkn…
