A novel quasi-one-dimensional topological insulator in bismuth iodide beta-Bi4I4

László Forró, Marco Grioni, Oleg Yazyev, Luca Moreschini, Gabriel Albert Autes, Andrea Pisoni, Jens Christian Johannsen, Wentao Zhang

Recent progress in the field of topological states of matter(1,2) has largely been initiated by the discovery of bismuth and antimony chalcogenide bulk topological insulators (TIs; refs 3-6), followed by closely related ternary compounds(7-16) and predicti ...

Surface functionalization of dinuclear clathrochelates via Pd-catalyzed cross-coupling reactions: facile synthesis of polypyridyl metalloligands

Rosario Scopelliti, Kay Severin, Philip Pattison, Euro Solari, Giacomo Cecot, Mathieu Jérémie Marmier

Dinuclear clathrochelate complexes are easily accessible by reaction of zinc(II) triflate or cobalt(II) nitrate with arylboronic acids and phenoldioximes. The utilization of brominated arylboronic acids and/or brominated phenoldioximes allows preparing cla ...

Design strategy for controlled natural aging in Al-Mg-Si alloys

William Curtin

This study presents a design strategy for Al-Mg-Si alloys to control natural aging. Recently, trace addition of Sn was shown to suppress natural aging for up to two weeks, which was explained by the strong trapping of vacancies to Sn atoms. Here we explore ...

Field-enhanced design of steep-slope VO2 switches for low actuation voltage

Juan Ramon Mosig, Mihai Adrian Ionescu, Clara-Fausta Moldovan, Michele Tamagnone, Wolfgang Amadeus Vitale, Emanuele Andrea Casu, Luca Petit

The abrupt metal-insulator transition in vanadium dioxide (VO2) offers novel performance and functionality for beyond CMOS switches, enabling simultaneous high ON current and ultra-steep subthreshold slope with low temperature dependence. We developed a fi ...

Photoinduced Absorption Spectroscopy of CoPi on BiVO4: The Function of CoPi during Water Oxidation

Florian Le Formal, Yimeng Ma

This paper employs photoinduced absorption and electrochemical techniques to analyze the charge carrier dynamics that drive photoelectrochemical water oxidation on bismuth vanadate (BiVO4), both with and without cobalt phosphate (CoPi) co-catalyst. These r ...

Surface States Transport in Topological Insulator Bi0.83Sb0.17 Nanowires

Jean-Philippe Ansermet

We investigate the transport properties of topological insulator (TI) nanowires. Single-crystal nanowire samples with diameters ranging from 75 nm to 1.1 m are prepared using high frequency liquid phase casting in a glass capillary; cylindrical single crys ...

Primordial metallic melt in the deep mantle

Susannah McGregor Dorfman

Seismic tomography models reveal two large low shear velocity provinces (LLSVPs) that identify large-scale variations in temperature and composition in the deep mantle. Other characteristics include elevated density, elevated bulk sound speed, and sharp bo ...

Thermal diffusivity measurements of templated nanocomposite using infrared thermography

Arnaud Magrez, Helmuth Berger, Philippe Bugnon, Manish Sharma

Electrodeposited bismuth telluride (Bi2Te3) nanowires using anodic alumina (AAO) templates show anisotropic thermal properties in a direction parallel and perpendicular to the nanowire/nanochannel axis. The present study reports thermal diffusivity measure ...
