Probing Nanogap-Dependent Plasmonic Coupling in Gold Nanoparticle Superlattices by Scanning Tunneling Microscopy Induced Light Emission

Olivier Martin

Plasmonic nanogaps can support confined and enhanced electromagnetic fields. In this work, we use scanning tunneling microscopy-induced light emission (STM-LE) to study the localized surface plasmon resonance of gold nanoparticle superlattices, which consi ...

Organometallic Ir(iii) complexes: post-synthetic modification, photophysical properties and binuclear complex construction

Anastasia Gitlina

Two methods of post-synthetic modification (Suzuki coupling and CuAAC click-reaction) were applied to Ir(iii) complexes Ir((CN)-N-)(2)(NN)-N- to provide the second highly selective donor site. One family of functionalized complexes was used to d ...

From pulsed-DCMS and HiPIMS to microwave plasma-assisted sputtering: Their influence on the properties of diamond-like carbon films

Aïcha Hessler-Wyser, Johann Michler, Caroline Hain

The fabrication of high-hardness non-hydrogenated diamond-like carbon (DLC) via standard magnetron sputtering (MS) is often hindered by the low sputtering yields and ionisation rates of carbon, therefore investigations into pulsed alternatives of MS, else ...

Magnetic Field Induced Quantum Spin Liquid in the Two Coupled Trillium Lattices of K2Ni2(SO4)(3)

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Peter Babkevich, Luc Testa, Virgile Yves Favre, Nagabhushan Ganesh Hegde

Quantum spin liquids are exotic states of matter that form when strongly frustrated magnetic interactions induce a highly entangled quantum paramagnet far below the energy scale of the magnetic interactions. Three-dimensional cases are especially challengi ...

Benzodithiophene‐Based Spacers for Layered and Quasi‐Layered Lead Halide Perovskite Solar Cells

Liang Yao, Kevin Sivula, Jun Ho Yum, Nestor Guijarro Carratala, Mounir Driss Mensi, Han-Hee Cho, Barbara Alexandra Primera Darwich

Incorporating extended pi-conjugated organic cations in layered lead halide perovskites is a recent trend promising to merge the fields of organic semiconductors and lead halide perovskites. Herein, we integrate benzodithiophene (BDT) into Ruddlesden–Poppe ...

A new characterization approach to study the mechanical behavior of silicon nanowires

Yusuf Leblebici, Zuhal Tasdemir

This work proposes a new approach to characterize the mechanical properties of nanowires based on a combination of nanomechanical measurements and models. Silicon nanowires with a critical dimension of 90 nm and a length of 8 mu m obtained through a monoli ...

Broken-Symmetry Ground States of the Heisenberg Model on the Pyrochlore Lattice

Giuseppe Carleo

The spin-1/2 Heisenberg model on the pyrochlore lattice is an iconic frustrated three-dimensional spin system with a rich phase diagram. Besides hosting several ordered phases, the model is debated to possess a spin-liquid ground state when only nearest-ne ...

Alignment interactions drive structural transitions in biological tissues

Ignacio Pagonabarraga Mora

Experimental evidence shows that there is a feedback between cell shape and cell motion. How this feedback impacts the collective behavior of dense cell monolayers remains an open question. We investigate the effect of a feedback that tends to align the ce ...

Geometric landscapes for material discovery within energy–structure–function maps

Berend Smit, Seyedmohamad Moosavi, Henglu Xu

Porous molecular crystals are an emerging class of porous materials formed by crystallisation of molecules with weak intermolecular interactions, which distinguishes them from extended nanoporous materials like metal–organic frameworks (MOFs). To aid disco ...

Tracking attosecond electronic coherences using phase-manipulated extreme ultraviolet pulses

Marcel Drabbels, Primoz Rebernik Ribic

The recent development of ultrafast extreme ultraviolet (XUV) coherent light sources bears great potential for a better understanding of the structure and dynamics of matter. Promising routes are advanced coherent control and nonlinear spectroscopy schemes ...

Ultrafast Intersystem Crossing and Structural Dynamics of [Pt(ppy)(mu-(t)Bu(2)pz)](2)

Majed Chergui, Lars-Hendrik Mewes, Rebecca Ann Ingle

Intersystem crossing (ISC) rates of transition-metal complexes are determined by the complex interplay of a molecule's electronic and structural dynamics. To broaden our understanding of these key factors, we investigate the case of the prototypical d(8)-d ...

Assessing mobile ions contributions to admittance spectra and current-voltage characteristics of 3D and 2D/3D perovskite solar cells

Mohammad Khaja Nazeeruddin, Sanghyun Paek

Recently, the 2D perovskite layer is employed as a capping/passivating layer in the perovskite solar cells (PSCs). The 2D perovskite layer is prepared by inserting a large-sized hydrophobic cation spacer into the perovskite crystal lattice. The large-sized ...
