Oxidation States, Thouless' Pumps, and Nontrivial Ionic Transport in Nonstoichiometric Electrolytes

Federico Grasselli

Thouless' quantization of adiabatic particle transport permits one to associate an integer topological charge with each atom of an electronically gapped material. If these charges are additive and independent of atomic positions, they provide a rigorous de ...

Chiral Spin-Wave Velocities Induced by All-Garnet Interfacial Dzyaloshinskii-Moriya Interaction in Ultrathin Yttrium Iron Garnet Films

Dirk Grundler, Ping Che, Peng Gao, Haiming Yu, Yuehui Li, Sa Tu, Jilei Chen, Jianyu Zhang, Song Liu, Tao Liu

Spin waves can probe the Dzyaloshinskii-Moriya interaction (DMI), which gives rise to topological spin textures, such as skyrmions. However, the DMI has not yet been reported in yttrium iron garnet (YIG) with arguably the lowest damping for spin waves. In ...

Metal-organic framework derived copper catalysts for CO2 to ethylene conversion

Jun Li, Ning Wang, Yun Liu

The electrochemical reduction of CO2 to ethylene provides a carbon-neutral avenue for the conversion of CO2 to value-added fuels and feedstocks, so contributing to the storage of intermittent renewable electricity. The exploration of efficient electrocatal ...

Metal Substitution as the Method of Modifying Electronic Structure of Metal–Organic Frameworks

Berend Smit, Fatmah Ebrahim, Christopher Patrick Ireland, Olga Syzgantseva

Targeted modification of electronic structure is an important step in the optimization of metal–organic frameworks (MOFs) for photovoltaic, sensing, and photocatalytic applications. The key parameters to be controlled include the band gap, the absolute ene ...

Insights into the interfacial carrier behaviour of copper ferrite ( CuFe2O4) photoanodes for solar water oxidation

Kevin Sivula, Liang Yao, Nestor Guijarro Carratala, Florian Le Formal, Yongpeng Liu, Florent Alexandre Boudoire

Designing efficient yet robust photoanodes for water oxidation stands out as a major bottleneck in the realization of a feasible photoelectrochemical tandem cell for solar water splitting. Spinel copper ferrite (CuFe2O4) has been recently reported as a pot ...

Non-destructive piezoelectric characterisation of Sc doped aluminium nitride thin films at wafer level

Paul Muralt, Stefan Mertin, Clemens Benedict Nyffeler, Andrea Mazzalai

Scandium doped aluminium nitride (ScAlN) gained much attention during last years, since its piezoelectric response is much enlarged as compared to pure AlN films. Above 30% Sc the films are of high interest for piezoMEMS sensing and actuation, ultrasound g ...

Ruthenium Oxide Nanosheets for Enhanced Oxygen Evolution Catalysis in Acidic Medium

Filip Mateusz Podjaski

The fabrication of highly active and robust hexagonal ruthenium oxide nanosheets for the electrocatalytic oxygen evolution reaction (OER) in an acidic environment is reported. The ruthenate nanosheets exhibit the best OER activity of all solution-processed ...

Mechanisms of the Antibacterial Effects of TiO2-FeOx under Solar or Visible Light: Schottky Barriers versus Surface Plasmon Resonance

Juan Kiwi, Sami Rtimi

This study reports the significant mechanistic difference between binary-oxide antibacterial films with the same composition but different microstructures. Binary TiO2-FeOx films were found to present a faster bacterial inactivation kinetics under visible ...

A Study on the Charge Carrier Transport of Passivating Contacts

Gizem Nogay

Recently, the charge carrier transport mechanism of passivating contacts, which feature an ultra-thin oxide layer, has been investigated by studying temperature-dependent current-voltage (I-V) characteristics. The measurement revealed that tunneling is the ...

Single step synthesis of Schottky-like hybrid graphene - titania interfaces for efficient photocatalysis

Aleksandra Radenovic

The development of 2D nanomaterial coatings across metal surfaces is a challenge due to the mismatch between the metal microstructure and the nanoscale materials. The naturally occurring thin oxidative layer present across all metal surfaces, may lead to l ...

Interplay of annealing temperature and doping in hole selective rear contacts based on silicon-rich silicon-carbide thin films

Christophe Ballif, Gizem Nogay, Franz-Josef Haug, Matthieu Despeisse, Monica Morales Masis, Philipp Friedrich Hermann Löper, Philippe Wyss, Oscar Esteban Rucavado Leandro, Josua Andreas Stückelberger

We present a detailed optimization of a hole selective rear contact for p-type crystalline silicon solar cells which relies on full-area processes and provides full-area passivation. The passivating hole-contact is based on a layer stack comprising a chemi ...
