Electrically tunable dipolar interactions between layer-hybridized excitons

Andras Kis, Fedele Tagarelli, Edoardo Lopriore

Transition-metal dichalcogenide bilayers exhibit a rich exciton landscape including layer-hybridized excitons, i.e. excitons which are of partly intra- and interlayer nature. In this work, we study hybrid exciton-exciton interactions in naturally stacked W ...

Nonlinear electro-mechanical coupling and thermally stimulated currents in relaxor ferroelectrics

Lukas Riemer

In this work, the emergence of polarization and electro-mechanical coupling in Pb(Mg1/3Nb2/3)O3 and Pb(Mg1/3Nb2/3)O3 â PbTiO3 was investigated by means of thermally stimulated current, and nonlinear dielectric and electro-mechanical measurements. The pre ...

Three-dimensional electrodes for dielectrophoretic applications

Kevin Keim

This thesis reports the use of metal-coated three-dimensional SU-8 electrodes for dielectrophoretic bio sensing and particle manipulation applications. Placing free standing three-dimensional electrodes in microfluidic channels, electric fields can be appl ...

Accurate molecular polarizabilities with coupled cluster theory and machine learning

Michele Ceriotti, David Mark Wilkins, Andrea Grisafi, Yang Yang

The molecular dipole polarizability describes the tendency of a molecule to change its dipole moment in response to an applied electric field. This quantity governs key intra- and intermolecular interactions, such as induction and dispersion; plays a vital ...

Novel Slanted Field Plate Technology for GaN HEMTs by Grayscale Lithography on Flowable Oxide

Elison de Nazareth Matioli, Jun Ma, Luca Nela, Taifang Wang

We report a novel process to achieve slanted field plate (S-FP), which is a field plate with a gradual increase thickness from gate edge towards drain - utilizing grayscale lithography on flowable oxide (FOX) in single process step, in which developed FOX ...

Rational design of a high-throughput droplet sorter

Tobias Schneider, Simon Sebastian Schütz

The high-throughput selection of individual droplets is an essential function in droplet-based microfluidics. Fluorescence-activated droplet sorting is achieved using electric fields triggered at rates up to 30 kHz, providing the ultra-high throughput rele ...

MyDEP: A New Computational Tool For Dielectric Modeling Of Particles And Cells

Philippe Renaud, Jonathan Bastien Cottet

Before performing experiments in the lab with dielectrophoresis (DEP), it is useful to predict the particle and cell responses to the electric field. This requires knowledge of particles or cells properties, which can be obtained from the literature, and i ...

Static Dielectric Permittivity of Ice from First Principles

Nicola Marzari, Nicéphore Arthur François Bonnet

The static permittivity of ice is computed from first principles as a function of the electric field, together with the generalized Kirkwood factor. The molecular dipole in ice is unambiguously obtained by an original method combining a slab approach and B ...
