Simultaneous electronic and magnetic excitation of cobalt by intense THz pulses

We study the interaction of intense THz magnetic fields with ferromagnetic thin films. At higher field intensities, the THz electric field starts playing a role, strongly changing the dielectric properties of the cobalt thin film. ...

Methods and systems for high bandwidth communications interface

Mohammad Amin Shokrollahi, Ali Hormati, Anant Pratap Singh

A pair of ground planes arranged in parallel, a dielectric medium disposed in between the pair of ground planes, and a set of at least four signal conductors disposed in the dielectric medium, the set of at least four signal conductors having (i) a first p ...

Does the real part contain all the physical information?

Olivier Martin

Polarisation charge formed on nanostructure surfaces upon optical excitation provides a useful tool to understand the underlying physics of plasmonic systems. Plasmonic simulations in the frequency domain typically calculate the polarisation charge as a co ...

Towards Flexible, Scalable and Low Loss Non-reciprocal System in Silicon Photonics

Christophe Marcel Georges Galland, Yang Liu

A silicon photonic non-reciprocal isolator/circulator system with time-dependent permittivity tensor is demonstrated. In addition to being broadband and low loss, the architecture is scalable to achieve high extinction ratio with reconfigurable isolation p ...

Two-dimensional Frohlich interaction in transition-metal dichalcogenide monolayers: Theoretical modeling and first-principles calculations

Thibault Daniel Pierre Sohier

We perform ab initio calculations of the coupling between electrons and small-momentum polar-optical phonons in monolayer transition-metal dichalcogenides of the 2H type: MoS2, MoSe2, MoTe2, WS2, and WSe2. The polar-optical coupling with longitudinal optic ...

Electrothermal actuation of vanadium dioxide for tunable capacitors and microwave filters with integrated microheaters

Mihai Adrian Ionescu, Andreas Schueler, Clara-Fausta Moldovan, Montserrat Fernandez-Bolanos Badia, Wolfgang Amadeus Vitale, Antonio Paone, Luca Petit

We report the fabrication, modeling and characterization of novel microwave tunable capacitors based on the metal-insulator transition (MIT) of Vanadium Dioxide (VO2) as a future replacement solution for microelectromechanical capacitive switches. We prese ...

Fabrication process of silicone-based dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Samuel Schlatter

This contribution demonstrates the fabrication process of dielectric elastomer transducers (DETs). DETs are stretchable capacitors consisting of an elastomeric dielectric membrane sandwiched between two compliant electrodes. The large actuation strains of ...

Design and fabrication of high-k filled sub-100 nm gap resonators with embedded dielectric field effect transistor for ultra high frequency applications

Mihai Adrian Ionescu, Mariazel de la Candelas Maqueda López, Montserrat Fernandez-Bolanos Badia, Wolfgang Amadeus Vitale, Emanuele Andrea Casu

A novel fabrication process for the integration of Field Effect Transistors in electrostatically actuated bulk acoustic resonators is demonstrated. ALD-deposited HfO2 is used as a high-k dielectric for the FET and as an etch-stop layer during the release o ...

Self-poling of BiFeO3 thick films

Dragan Damjanovic

Bismuth ferrite (BiFeO3) is difficult to pole because of the combination of its high coercive field and high electrical conductivity. This problem is particularly pronounced in thick films. The poling, however, must be performed to achieve a large macrosco ...
