Superconductivity-localization interplay and fluctuation magnetoresistance in epitaxial ${BaPb}_{1 - x} {Bi}_{x} O_{3}$ thin films

D. T. Harris, N. Campbell, R. Uecker, M. Brützam, D. G. Schlom, A. Levchenko, M. S. Rzchowski, and C.-B. Eom

Phys. Rev. Materials 2, 041801(R) (2018) - Published 16 April, 2018

Doped BaBiO $_{3}$ superconductors have for a long time attracted the interest of the condensed matter community due to the surprisingly high Tc, proximity to a charge-ordered phase, and similarities to the high-Tc cuprates in an isotropic, nonmagnetic system. In this work, the authors use the thickness of epitaxial BaPb $_{1 - x}$ Bi $_{x}$ O $_{3}$ films to drive a superconductor-insulator transition with disorder. Above Tc, magnetoresistance measurements show superconducting fluctuations that extend to remarkably high temperatures for the thickest films. These findings demonstrate both the important role of disorder in BaBiO $_{3}$ superconductors, as well as the potential for this class of materials to serve as an important bridge between high-Tc cuprates and disordered conventional superconductors.

Progressive friction mobilization and enhanced Janssen's screening in confined granular rafts

Oscar Saavedra V., Hervé Elettro, and Francisco Melo

Phys. Rev. Materials 2, 043603 (2018) - Published 25 April, 2018

Confined granular materials are known to undergo exponential screening of surface stresses due to particle-wall friction. Here, the authors investigate the transition to the friction-dominated jammed state and map the gradual development of the internal stress profile with flexible pressure sensors. Surprisingly, they observe that screening builds up much more slowly than previously thought. They explain this behavior in terms of progressive friction mobilization, where the full amplitude of the frictional forces is only reached after a macroscopic local displacement. At further stages of compression, the authors find that a gradient of elastic modulus may exist in large aspect ratio confinements. This dramatically enhances the local screening, well beyond the full mobilization limit described by Janssen’s model.

Engineering hybrid epitaxial InAsSb/Al nanowires for stronger topological protection

Joachim E. Sestoft, Thomas Kanne, Aske Nørskov Gejl, Merlin von Soosten, Jeremy S. Yodh, Daniel Sherman, Brian Tarasinski, Michael Wimmer, Erik Johnson, Mingtang Deng, Jesper Nygård, Thomas Sand Jespersen, Charles M. Marcus, and Peter Krogstrup

Phys. Rev. Materials 2, 044202 (2018) - Published 12 April, 2018

Topological protection in hybrid semiconductor-superconductor materials largely relies on the hybrid electronic properties. This paper presents growth and characterization of epitaxial InAs $_{1 - x}$ Sb $_{x}$ /Al nanowires where both composition and crystal structure of the semiconductor is varied. Among the findings are a strong spin-orbit coupling at intermediate compositions, large effective $g$ factors, induced hard-gap superconductivity in nanowires with both zincblende and wurtzite structure, and signatures of topological superconductivity

Tailoring band structure and band filling in a simple cubic (IV, III)-VI superconductor

M. Kriener, M. Kamitani, T. Koretsune, R. Arita, Y. Taguchi, and Y. Tokura

Phys. Rev. Materials 2, 044802 (2018) - Published 25 April, 2018

A demanding issue in superconductivity is to enhance the transition temperature Tc. One mechanism discussed is the possibly positive effect of valence-skipping elements. In this work, the authors successfully demonstrated that Tc can be enhanced to almost 6 K by doping valence-skipping In and codoping Se into the simple cubic chalcogenide SnTe. To maintain the cubic structure necessary for the superconductivity, the authors employed a high-pressure synthesis method yielding single-phase solid solutions Sn $_{1}$ $_{-}$ $_{x}$ In $_{x}$ Te $_{1}$ $_{-}$ $_{y}$ Se $_{y}$ over a wide composition range revealing an unexpected two-dome structure of the phase diagram Tc( $x, y = 0$ ). The overall superconducting phase diagram is well supported by first-principles density-functional calculations.
