Enhanced photon emission from site- and energy-controlled InGaAs/GaAs quantum dots coupled to GaAs nanowires

InGaAs/GaAs quantum dots (QDs) embedded in a GaAs substrate are very useful photon sources, including single and entangled photons, due to their unperturbed environment. Contrary to self-formed QDs, those grown in pyramidal pits can be well controlled in p ...

In Situ Synthesis of CuxO/N Doped Graphdiyne with Pyridine N Configuration for Ammonia Production via Nitrate Reduction

Sophia Haussener, Jian Li, Roberto Valenza

Electroreduction of nitrate to ammonia provides an interesting pathway for wastewater treatment and valorization. Cu-based catalysts are active for the conversion of NO3− to NO2− but suffer from an inefficient hydrogenation process of NO2−. Herein, CuxO/N- ...

Efficient and Stable Perovskite Solar Cells by Tailoring of Interfaces

Mohammad Khaja Nazeeruddin, Jianxing Xia

The interface tailoring is crucial for the efficiency and stability of Perovskite Solar Cells (PSCs). The reported interface engineering primarily focuses on the energy level turning and trap state passivation to improve the photovoltaic performance of PSC ...

Interactions between aluminium and fired passivating contacts during fire-through metallization

Christophe Ballif, Franz-Josef Haug, Aïcha Hessler-Wyser, Mario Joe Lehmann, Sofia Libraro

Replacing silver metallization with earth-abundant materials in Si solar cells is a critical step towards the sustainable growth of photovoltaics. In this work, we investigate fire-through processes using Al for the metallization of solar cells with p-type ...

Wigner Gaussian dynamics: Simulating the anharmonic and quantum ionic motion

Lorenzo Monacelli

The atomic motion controls important properties of materials, such as thermal transport, phase transitions, and vibrational spectra. However, simulating the ionic dynamics is exceptionally challenging when quantum fluctuations are relevant (e.g., at low te ...

Electronic transport and magnetism in the alternating stack of metallic and highly frustrated magnetic layers in Co(1/3)NbS(2)

László Forró, Helmuth Berger, Henrik Moodysson Rønnow, Ivica Zivkovic, Jacim Jacimovic, Julian Piatek, Nikolay Tsyrulin

Transition-metal dichalcogenides (TMDs) are layered compounds that support many electronic phases, including various charge density waves, superconducting, and Mott insulating states. Their intercalation with magnetic ions introduces magnetic sublayers, wh ...

Emergent XY* transition driven by symmetry fractionalization and anyon condensation

Andreas Martin Läuchli Herzig

Anyons in a topologically ordered phase can carry fractional quantum numbers with re-spect to the symmetry group of the considered system, one example being the fractional charge of the quasiparticles and quasiholes in the fractional quantum Hall effect. W ...

Ultrarapid crystallization of low-dimensional perovskite with excellent stability for future high-throughput fabrication

Mohammad Khaja Nazeeruddin, Yi Zhang

Perovskite solar cells (PSCs) as an emerging photovoltaic technique have achieved exceptional power conversion efficiency (PCE) up to 25.7% after fast development over the past decade. But currently some critical issues are still not well addressed in term ...

Search for the decay B-s(0) -> eta eta

Olivier Schneider

We report results from a search for the decay B-s(0) -> eta eta using 121.4 fb(-1) of data collected at the Upsilon(5S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We do not observe any signal and set an upper limit o ...

Substrate-controlled C-H or C-C alkynylation of cyclopropanes: generation of aryl radical cations by direct light activation of hypervalent iodine reagents

Jérôme Waser, Matthew Wodrich, Vu Trung Tin Nguyen

We report the first oxidative C-H alkynylation of arylcyclopropanes. Irradiation of ethynylbenziodoxolone (EBX) reagents with visible light at 440 nm promoted the reaction. By the choice of the aryl group on the cyclopropane, it was possible to completely ...

Dynamical Control of Nuclear Isomer Depletion via Electron Vortex Beams

Fabrizio Carbone, Simone Gargiulo

Some nuclear isomers are known to store a large amount of energy over long periods of time, with a very high energy-to-mass ratio. Here, we describe a protocol to achieve the external control of the isomeric nuclear decay by using electron vortex beams who ...

Integrated solar-driven high-temperature electrolysis operating with concentrated irradiation

Jan Van Herle, Sophia Haussener, Stefan Diethelm, Meng Lin, Clemens Gregor Suter

High-temperature electrolysis for reducing H2O (and CO2) to H2 (and CO) converts concentrated solar energy into fuels and chemical feedstock. We invented an integrated reactor concept comprising a solar cavity receiver for reactant heating, a solid oxide e ...
