Phase transitions, screening and dielectric response of CsPbBr3

Cesium-lead-bromide (CsPbBr3) is the simplest all inorganic halide perovskite. It serves as a reference material for understanding the exceptional solar cell properties of the organic-inorganic hybrid halide perovskites and is itself discussed as an altern ...

Linear studies of spurious backward-wave instabilities in a dielectric-loaded smooth-wall gyrotron beam ducts

Stefano Alberti, Jean-Philippe Hogge, Jérémy Genoud

Recently developed self-consistent models for beam-wave interaction simulations of a gyrotron oscillator have been extended to study spurious backward-wave instabilities in smooth-wall circular symmetric beam ducts. Starting from a purely metallic case, th ...

Finite-size corrections of defect energy levels involving ionic polarization

Alfredo Pasquarello, Stefano Falletta, Julia Anna Wiktor

We develop a scheme for finite-size corrections of vertical transition energies and single-particle energy levels involving defect states with built-in ionic polarization in supercell calculations. The method accounts on an equal footing for the screening ...

SIMPLE code: Optical properties with optimal basis functions

Nicola Marzari, Gianluca Prandini, Paolo Umari

We present SIMPLE, a code developed to calculate optical properties of metallic and insulating extended systems using the optimal basis method originally proposed by E.L. Shirley in 1996. Two different approaches for the evaluation of the complex dielectri ...

Grand canonical simulations of electrochemical interfaces in implicit solvation models

Nicola Marzari, Oliviero Andreussi, Nicolas Georg Hörmann

We discuss grand canonical simulations based on density-functional theory to study the thermodynamic properties of electrochemical interfaces of metallic electrodes in aqueous environments. Water is represented using implicit solvation, here via the self-c ...

Study of self-sensing actuation strategies for quasi-static piezoelectric actuators

Yves Perriard, Louis Antoine Masson

Self-sensing actuation in piezoelectric actuators has been a growing research topic since 1992, with two main approaches having been identified: either by evaluating the dielectric displacement field within the piezoelectric through a measurement bridge, e ...

Modeling Dielectric Constant Variability in Aggregate Polymers from CV Measurements

Marco Mattavelli, Jean-Michel Sallese, Catherine Dehollain, Diego Ruben Barrettino

Recently a new technique based on capacitive sensing has been developed and used to estimate the amount of moisture in polymers by means of the deviation of the dielectric constant. This technique is expected to be used for in-line monitoring of aggregate ...

MyDEP: A New Computational Tool for Dielectric Modeling of Particles and Cells

Philippe Renaud, Jonathan Bastien Cottet

Dielectrophoresis (DEP) and electrorotation (ROT) are two electrokinetic phenomena exploiting nonuniform electric fields to exert a force or torque on biological particles suspended in liquid media. They are widely used in lab-on-chip devices for the manip ...

Artificial Muscles: Dielectric Elastomers Responsive to Low Voltages

Yauhen Sheima

The lack of soft high-dielectric-permittivity elastomers responsive to a low voltage has been a long-standing obstacle for the industrialization of dielectric elastomer actuators (DEA) technology. Here, elastomers that not only possess a high dielectric pe ...
