Sequential Carrier Transfer Can Accelerate Triplet Energy Transfer from Functionalized CdSe Nanocrystals

Nanocrystal (NC)-sensitized triplet-fusion upconversion is a rising strategy to convert long-wavelength, incoherent light into higher-energy output photons. Here, we chart the photophysics of tailor-functionalized CdSe NCs to understand energy transfer to ...

Fast evaluation of spherical harmonics with sphericart

Michele Ceriotti, Guillaume André Jean Fraux, Filippo Bigi

Spherical harmonics provide a smooth, orthogonal, and symmetry-adapted basis to expand functions on a sphere, and they are used routinely in physical and theoretical chemistry as well as in different fields of science and technology, from geology and atmos ...

Nanosegregation in arene-perfluoroarene pi-systems for hybrid layered Dion-Jacobson perovskites

Michael Graetzel, Shaik Mohammed Zakeeruddin, Pascal Alexander Schouwink, Lukas Pfeifer, Jovana Milic, Laura Piveteau, Masaud Hassan S Almalki, Algirdas Ducinskas

Layered hybrid perovskites are based on organic spacers separating hybrid perovskite slabs. We employ arene and perfluoroarene moieties based on 1,4-phenylenedimethylammonium (PDMA) and its perfluorinated analogue (F-PDMA) in the assembly of hybrid layered ...

Unraveling the origin of the peculiar transition in the magnetically ordered phase of theWeyl semimetal Co3Sn2S2

Henrik Moodysson Rønnow, Oleg Yazyev, Ivica Zivkovic, Jian Rui Soh, Ravi Yadav

The recent discovery of topologically nontrivial behavior in Co3Sn2S2 stimulated a notable interest in this itinerant ferromagnet (T-C = 174 K). The exact magnetic state remains ambiguous, with several reports indicating the existence of a second transitio ...

Soft-mode dynamics and sublattice polarization in an archetypal antiferroelectric

Helmuth Berger

Terahertz and far-infrared techniques are combined with complementary Raman and inelastic neutron scattering results to probe the low-energy phonon dynamics of archetypal antiferroelectric candidate - francisite (Cu3Bi(SeO3)(2)O2Cl). The combined results c ...

A Machine Learning Model of Chemical Shifts for Chemically and Structurally Diverse Molecular Solids

Artur Andrzej Stefaniuk, David Lyndon Emsley, Michele Ceriotti, Manuel Cordova, Albert Hofstetter, Federico Maria Paruzzo

Nuclear magnetic resonance (NMR) chemical shifts are a direct probe of local atomic environments and can be used to determine the structure of solid materials. However, the substantial computational cost required to predict accurate chemical shifts is a ke ...

Design Space of Negative Capacitance in FETs

Jean-Michel Sallese, Farzan Jazaeri

Relying on the previously developed charge-based approaches, this paper presents a physics-based design space of negative capacitance in double-gate and bulk MOSFET architectures. The impact of thickness variation of the ferroelectric on the DC characteris ...

Spatial Modulation of Vibrational and Luminescence Properties of Monolayer MoS & x2082; Using a GaAs Nanowire Array

Anna Fontcuberta i Morral, Wonjong Kim, Jean-Baptiste Leran, Mirjana Dimitrievska, Lucas Güniat, Didem Dede, Valerio Piazza, Akshay Balgarkashi

The integration of transition-metal dichalcogenides (TMDs) with non-planar substrates such as nanopillars provides a way to spatially modify the optical properties mainly through the localized strain. Similar studies to date have utilized insulating SiO2 n ...

Nanopore Generation in Biodegradable Silk/Magnetic Nanoparticle Membranes by an External Magnetic Field for Implantable Drug Delivery

Jürgen Brugger, Giovanni Boero, Xiao Sheng Zhang, Ya Wang

Implantable devices for localized and controlled drug release are important, e.g., for therapies of cancer and chronic pain. However, most of the existing active implants are limited by the usage of nonbiodegradable materials; thus, surgery is needed to ex ...
