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…
Autonomous X-ray Fluorescence Mapping of Chemically Heterogeneous Systems via a Correlative Feature Detection Framework
Carlos Deleon, Dmitri Gavrilov, Peggy ODay +1
We present X-AutoMap, a modular framework for autonomous X-ray fluorescence (XRF) mapping that enables chemically informed targeting of regions of interest through a correlative fe…
Alloying Effects on the Microstructure and Properties of Laser Additively Manufactured Tungsten Materials
W. Streit Cunningham, Eric Lang, David J. Sprouster +6
A large body of literature within the additive manufacturing (AM) community has focused on successfully creating stable tungsten (W) microstructures due to significant interest in…
Detection Sensitivity Limit of Hundreds of Atoms with X-Ray Fluorescence Microscopy
Mateus G. Masteghin, Toussaint Gervais, Steven K. Clowes +10
We report X-ray fluorescence (XRF) imaging of nanoscale inclusions of impurities for quantum technology. A very bright diffraction-limited focus of the X-ray beam produces very hig…
Symmetry-specific characterization of bond orientation order in DNA-assembled nanoparticle lattices
Jack A. Logan, Aaron Michelson, Ajith Pattammattel +3
Bond-orientational order in DNA-assembled nanoparticle lattices is explored with the help of recently introduced Symmetry-specific Bond Order Parameters (SymBOPs). This approach pr…
Proton distribution visualization in perovskite nickelate devices utilizing nanofocused X-rays
Ivan A. Zaluzhnyy, Peter O. Sprau, Richard Tran +17
We use a 30-nm x-ray beam to study the spatially resolved properties of a SmNiO-based nanodevice that is doped with protons. The x-ray absorption spectra supported by density-f…
