Unveiling the Nature of Charge Carrier Interactions by Electroabsorption Spectroscopy: An Illustration with Lead-Halide Perovskites

Jacques-Edouard Moser, Joël Teuscher, Marine Eva Fedora Bouduban, Andrés Burgos Caminal

Unravelling the nature of the interactions between photogenerated charge carriers in solar energy conversion devices is key to enhance performance. In this perspective, we discuss electroabsorption spectroscopy (EAS), as the spectral bandshape of the elect ...

Enhancing model-based feedback perimeter control with data-driven online adaptive optimization

Nikolaos Geroliminis, Anastasios Kouvelas, Mohammadreza Saeedmanesh

Most feedback perimeter control approaches that are based on the Macroscopic Fundamental Diagram (MFD) and are tested in detailed network structures restrict inflow from the external boundary of the network. Although such a measure is beneficial for the ne ...

Constant-pressure nested sampling with atomistic dynamics

Robert John Nicholas Baldock

The nested sampling algorithm has been shown to be a general method for calculating the pressure-temperature-composition phase diagrams of materials. While the previous implementation used single-particle Monte Carlo moves, these are inefficient for conden ...

On the debris-level origins of adhesive wear

Jean-François Molinari, Ramin Aghababaei, Derek Warner

Every contacting surface inevitably experiences wear. Predicting the exact amount of material loss due to wear relies on empirical data and cannot be obtained from any physical model. Here, we analyze and quantify wear at the most fundamental level, i.e., ...

Dark excitons and the elusive valley polarization in transition metal dichalcogenides

Andras Kis, Dumitru Dumcenco, Yen-Cheng Kung, Alessandro Surrente

A rate equation model for the dark and bright excitons kinetics is proposed which explains the wide variation in the observed degree of circular polarization of the PL emission in different TMDs monolayers. Our work suggests that the dark exciton states pl ...

Phace: Physics-based Face Modeling and Animation

Mark Pauly, Ladislav Kavan, Alexandru Eugen Ichim

We present a novel physics-based approach to facial animation. Contrary to commonly used generative methods, our solution computes facial expressions by minimizing a set of non-linear potential energies that model the physical interaction of passive flesh, ...

Strongly bound excitons in anatase TiO2 single crystals and nanoparticles

Majed Chergui, Marco Grioni, Arnaud Magrez, Helmuth Berger, Edoardo Baldini, Simon Karl Moser, Gerald Auböck

Anatase TiO2 is among the most studied materials for light-energy conversion applications, but the nature of its fundamental charge excitations is still unknown. Yet it is crucial to establish whether light absorption creates uncorrelated electron-hole pai ...

Determining the nature of excitonic dephasing in high-quality GaN/AlGaN quantum wells through time-resolved and spectrally resolved four-wave mixing spectroscopy

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Eric Feltin

Applying four-wave mixing spectroscopy to a high-quality GaN/AlGaN single quantum well, we report on the experimental determination of excitonic dephasing times at different temperatures and exciton densities in IIInitride heterostructures. By comparing th ...

Control of the interaction strength of photonic molecules by nanometer precise 3D fabrication

Jürgen Brugger, Yuliya Lisunova

Applications for high resolution 3D profiles, so-called grayscale lithography, exist in diverse fields such as optics, nanofluidics and tribology. All of them require the fabrication of patterns with reliable absolute patterning depth independent of the su ...
