P-Dopant with Spherical Anion for Stable n-i-p Perovskite Solar Cells

Li-TFSI/t-BP is the most widely utilized p-dopant for hole-transporting materials (HTMs) in state-of-the-art perovskite solar cells (PSCs). However, its nonuniformity of doping, along with the hygroscopicity and migration of dopants, results in the devices ...

Surface functionalization strategies for optimal DNA conjugation on sensing surfaces for virus detection

Perrine Agnes Edith Robin

The COVID-19 pandemic has highlighted the need for new biodetection methods that would enable mass population screening, and help controlling the spread of viral diseases. Such technologies could benefit the prevention of many other infectious diseases. Fo ...

Review: III-V infrared emitters on Si: fabrication concepts, device architectures and down-scaling with a focus on template-assisted selective epitaxy

Kirsten Emilie Moselund

The local integration of III-Vs on Si is relevant for a wide range of applications in electronics and photonics, since it combines a mature and established materials platform with desired physical properties such as a direct and tuneable bandgap and high m ...

Difference in Intestine Content of Caenorhabditis elegans When Fed on Non-Pathogenic or Pathogenic Bacteria

Martinus Adela Maria Gijs, Farzad Rezaeianaran

We investigated the bacterial food digestion and accumulation in wild-type adult Caenorhabditis elegans (C. elegans) worms that have fed on either non-pathogenic RFP-expressing Escherichia coli (E. coli) OP50 or pathogenic-RFP-expressing Pseudomonas aerugi ...

A Kirchhoff-like theory for hard magnetic rods under geometrically nonlinear deformation in three dimensions

Pedro Miguel Nunes Pereira de Almeida Reis, Matteo Pezzulla

Magneto-rheological elastomers (MREs) are functional materials that can be actuated by applying an external magnetic field. MREs comprise a composite of hard magnetic particles dispersed into a nonmagnetic elastomeric (soft) matrix. Hard MREs have been rec ...

Role of intercalated cobalt in the electronic structure of Co1/3NbS2

László Forró, Helmuth Berger

Co1/3NbS2 is the magnetic intercalate of 2H-NbS2 where electronic itinerant and magnetic properties strongly influence each other throughout the phase diagram. Here we report the angle-resolved photoelectron spectroscopy (ARPES) study in Co1/3NbS2. In agre ...

In operando charge transport imaging of atomically thin dopant nanostructures in silicon

Gabriel Aeppli

Novel approaches to materials design, fabrication processes and device architectures have accelerated next-generation electronics component production, pushing device dimensions down to the nano- and atomic-scale. For device metrology methods to keep up wi ...

Mott versus Hybridization Gap in the Low-Temperature Phase of 1T-TaS2

Oleg Yazyev, Diego José Pasquier

We address the long-standing problem of the ground state of 1T-TaS2 by computing the correlated electronic structure of stacked bilayers using the GW + EDMFT method. Depending on the surface termination, the semi-infinite uncorrelated system is either band ...

Bootstrapping the a-anomaly in 4d QFTs

João Miguel Augusto Penedones Fernandes, Biswajit Sahoo, Jan Krzysztof Marucha

We study gapped 4d quantum field theories (QFTs) obtained from a relevant deformation of a UV conformal field theory (CFT). For simplicity, we assume the existence of a Z(2) symmetry and a single Z2-odd stable particle and no Z(2)-even particles at low ene ...

Unified Discrete Multisymplectic Lagrangian Formulation for Hyperelastic Solids and Barotropic Fluids

François Marie Alain Demoures

We present a geometric variational discretization of nonlinear elasticity in 2D and 3D in the Lagrangian description. A main step in our construction is the definition of discrete deformation gradients and discrete Cauchy-Green deformation tensors, which a ...

Exploring the robust extrapolation of high-dimensional machine learning potentials

Kevin Rossi

We show that, contrary to popular assumptions, predictions from machine learning potentials built upon highdimensional atom-density representations almost exclusively occur in regions of the representation space which lie outside the convex hull defined by ...

A splitting method for the numerical simulation of free surface flows with sediment deposition and resuspension

Marco Picasso, Arwa Mrad

We present a numerical model for the simulation of 3D sediment transport in a Newtonian flow with free surfaces. The Navier-Stokes equations are coupled with the transport, deposition, and resuspension of the particle concentrations, and a volume-of-fluid ...
