Oxygen DX center in In0.17Al0.83N: Nonradiative recombination and persistent photoconductivity

Alfredo Pasquarello, Giacomo Francesco Leonardo Miceli, Rocco Meli

Using a hybrid density-functional scheme, we address the O impurity substitutional to N (O-N) in In0.17Al0.83N. Our modelling supports In clustering to account for the strong band-gap bowing observed in InxAl1-xN alloys. To study the ON defect in In0.17Al0 ...

Scaling trends and performance evaluation of 2-dimensional polarity-controllable FETs

Giovanni De Micheli, Giovanni Vincenzo Resta, Pierre-Emmanuel Julien Marc Gaillardon

Two-dimensional semiconducting materials of the transition-metal-dichalcogenide family, such as MoS2 and WSe2, have been intensively investigated in the past few years, and are considered as viable candidates for next-generation elect ...

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

László Forró, Marco Grioni, Oleg Yazyev, Gabriel Albert Autes, Luca Moreschini, 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 ...

Hybrid organic-inorganic H-2-evolving photocathodes: understanding the route towards high performance organic photoelectrochemical water splitting

Michael Graetzel, Matthew Thomas Mayer, Marcel Roland Schreier

A promising, yet challenging, route towards renewable production of hydrogen is the direct conversion of solar energy at a simple and low cost semiconductor/water junction. Despite the theoretical simplicity of such a photoelectrochemical device, different ...

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 ...
