Surface Platinum Alloying for Passivation of Oxide Interfaces on Superconducting Niobium Films
Ananya Chattaraj, Conan Weiland, Bruce Ravel +10
Dielectric loss arising from two-level systems (TLS) at surfaces and interfaces remains a primary limitation to coherence in superconducting transmon qubits. Niobium (Nb), a widely…
Temperature-Dependent Dielectric Function of Tantalum Nitride Formed by Atomic Layer Deposition for Tunnel Barriers in Josephson Junctions
Ekta Bhatia, Aaron Lopez Gonzalez, Yoshitha Hettige +9
We report the dielectric functions of insulating tantalum nitride (TaN) films, deposited using atomic layer deposition (ALD) on 300 mm Si/SiO2 substrates, to demonstrate their suit…
Nucleation and Antiphase Twin Control in BiSe via Step-Terminated AlO Substrates
Alessandro R. Mazza, Jia Shi, Gabriel A. Vázquez-Lizardi +18
The epitaxial synthesis of high-quality 2D layered materials is an essential driver of both fundamental physics studies and technological applications. BiSe, a prototypical…
Polymer-Iron Oxide Hybrid Films for Controlling Electrokinetic Properties
Austin Dick, Xiao Tong, Kim Kisslinger +2
Electrokinetic phenomena at polymer-water interfaces are central to technologies for water purification, ion separations, and energy conversion, yet the ability to systematically c…
Observing Differential Spin Currents by Resonant Inelastic X-ray Scattering
Yanhong Gu, Joseph Barker, Jiemin Li +12
Controlling spin currents, i.e., the flow of spin angular momentum, in small magnetic devices is the principal objective of spin electronics, a main contender for future energy eff…
Hydrazine-Free Precursor for Solution-Processed All-Inorganic Se and Se1-xTex Photovoltaics
Adam D. Alfieri, Swarnendu Das, Kim Kisslinger +5
Selenium (Se) has reemerged as a promising absorber material for indoor and tandem photovoltaics (PVs), and its alloys with Te (Se1-xTex) offer a widely tunable bandgap. Solution p…
