Breakdown development in a nanosecond pulsed dielectric barrier discharge in humid air in plane-to-plane geometry

We used the ns electric field induced second harmonic (EFISH) generation diagnostic to measure the electric field evolution in a 200 ns pulse, dielectric barrier, plane-to-plane discharge in humid air, on the time scale shorter than the laser pulse duratio ...

Aspects of Gauge Theories Vacua

Adrien Florio

This thesis is concerned with gauge theories, their complicated vacuum and resulting effects. After an introduction to the subject, it is divided into four parts. Firstly, we treat the problem of chiral charge dynamics at finite temperature. Quantum field ...

Kinetic approach to the Schwinger effect during inflation

Oleksandr Sobol

Using the kinetic approach, we study the impact of the charged particle dynamics due to the Schwinger effect on the electric field evolution during inflation. As a simple model of the electric field generation, we consider the kinetic coupling of the elect ...

On the Dynamic Performance of Laterally Gated Transistors

Elison de Nazareth Matioli, Armin Jafari, Catherine Erine, Giovanni Santoruvo, Mohammad Samizadeh Nikooytabalvandani

Laterally gated transistors have been proposed as an innovative device architecture in which a semiconducting channel is controlled by side gates. In this sense, the gate can either be in contact with the sidewalls or be separated by a gap. In the latter c ...

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 ...

Charge generation by ultra-stretchable elastomeric electrets

Frank Nüesch, Yee Song Ko

Novel piezoelectric elastomers are synthesized and their long term stability and piezoelectric properties are investigated. They are thin film composites of specially designed polymer nanoparticles with high glass transition temperatures (T-g) and side gro ...

Estimation of Relative Position and Coordination of Mobile Underwater Robotic Platforms through Electric Sensing

Auke Ijspeert, Yannick Morel, Mathieu Porez

In the context of underwater robotics, positioning and coordination of mobile agents can prove a challenging problem. To address this issue, we propose the use of electric sensing, with a technique inspired by weakly electric fishes. In particular, the app ...

Third-Order Susceptibility of Silicon Crystals Measured with Millimeter-Wave Gyrotron

Jean-Philippe Hogge, Markus Siegrist

We investigate experimental dependence of the third harmonic generation efficiency in the n-type Si crystals on the geometrical dimensions of the sample, polarization and power of the fundamental wave. The efficiency increases monotonically with the rise o ...

Lightning Electromagnetic Fields at Very Close Distances Associated with Lightning Strikes to the Gaisberg Tower

Farhad Rachidi-Haeri, Marcos Rubinstein, Davide Pavanello, Pierre Zweiacker, Abdolhamid Shoory, Seyed Abbas Mosaddeghi

In this paper we present and discuss measurements of electric (vertical and radial) and magnetic fields from leaders and return strokes associated with lightning strikes to the 100 m tall Gaisberg tower in Austria obtained in 2007 and 2008. The fields were ...

Strong electric field and nonuniformity effects in GaN/AlN quantum dots revealed by high pressure studies

Nicolas Grandjean

The photoluminescence (PL) from GaN quantum dots (QDs) embedded in AlN has been investigated under hydrostatic pressure. The measured pressure coefficient of emitted light energy [dE(E)/dP] shows a negative value, in contrast with the positive pressure coe ...
