Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

The insertion of a metal-coated tip on the surface of a photonic crystal microcavity is used for simultaneous near field imaging of electric and magnetic fields in photonic crystal nanocavities, via the radiative emission of embedded semiconductor quantum ...

2012

Electric field distributions within lightning protection volume of a single lightning rod are studied for the case of a vertical downward leader. The boundaries of volumes with the electrical strength exceeding its critical value for ionization in air are ...

Electromagnetic Environment Associated with Lightning Strikes to Tall Strike Objects

Seyed Abbas Mosaddeghi

The study of the lightning interaction with tall strike objects has attracted considerable attention of lightning researchers lately. Many lightning measurements including current and associated electromagnetic fields were recently made all over the globe ...

On the use of the equal area rule for the wire-grid representation of metallic surfaces

Marcos Rubinstein, Abraham Rubinstein

This paper presents a brief theoretical discussion on the issue of the wire-grid representation of surfaces using the Numerical Electromagnetics Code (NEC). Different approaches for the determination of the parameters (in particular, the segment radii) of ...

Density functional theory with finite electric field

Alfredo Pasquarello

The method for treating finite electric fields within periodic boundary conditions is used to formally define a density functional depending on the electric field. An exchange and correlation energy functional depending on the electric field is introduced ...

Off-Gel[TM] electrophoresis

The Off-Gel™ technology is an isoelectric focusing (IEF) fractionation method which enables the purification of one or several proteins in a solution placed on an immobilised pH gradient (IPG) gel. The present thesis is devoted to its characterisation and ...

MOLED: simulation of multilayer organic light emitting diodes

Libero Zuppiroli, Marie-Noëlle Bussac, Eduard Tutis, Hocine Houili

MOLED solves the dynamics of electrons and holes in multilayer organic light emitting diodes (OLED). The carriers are injected on the positive and negative electrodes of the device by tunneling through a potential barrier. Thermal excitation processes acro ...

Dynamical monopoles and dipoles in a condensed molecular system: The case of liquid water

Alfredo Pasquarello

We propose a definition for the dipole of an individual molecule in a molecular solid or fluid. This problem is currently dealt with by partitioning-according to some prescription-the continuous electron density of the condensed phase. Instead, here we foc ...

Internal electric field and charge distribution in multilayer organic light-emitting diodes

Libero Zuppiroli, Detlef Berner, Eduard Tutis

The internal electric field in multilayer organic light-emitting diodes (OLEDs) is investigated using a combination of experimental measurement and numerical device modeling. This approach results in a detailed understanding of the functioning of a multila ...

Submicron metal-semiconductor-metal ultraviolet detectors based on AlGaN grown on silicon: Results and simulation

Nicolas Grandjean

Solar blind metal-semiconductor-metal detectors have been fabricated based on AlGaN grown on Si by molecular-beam epitaxy. Submicron finger spacings were obtained by electron-beam lithography, and allowed us to demonstrate a significant improvement of the ...
