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…
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…
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…
Atomic-scale mapping and quantification of local Ruddlesden-Popper phase variations
Erin E. Fleck, Berit H. Goodge, Matthew R. Barone +5
The Ruddlesden-Popper () compounds are a highly tunable class of materials whose functional properties can be dramatically impacted by their structural…
Titanium Contacts to Graphene: Process-Induced Variability in Electronic and Thermal Transport
Keren M. Freedy, Ashutosh Giri, Brian M. Foley +3
Contact Resistance (RC) is a major limiting factor in the performance of graphene devices. RC is sensitive to the quality of the interface and the composition of the contact, which…
