Upper critical field, pressure-dependent superconductivity and electronic anisotropy of Sm4Fe2As2Te1-xO4-yFy

László Forró, Richard Gaal, Bálint Náfrádi, Janusz Andrzej Karpinski, Andrea Pisoni, Sergiy Katrych, Péter Szirmai

We present a detailed study of the electrical transport properties of a recently discovered iron-based superconductor: Sm4Fe2As2Te0.72O2.8F1.2. We followed the temperature dependence of the upper critical field by resistivity measurement of single crystals ...

Scaling between magnetic field and temperature in the high-temperature superconductor BaFe2(As1−xP x )2

Philip Johannes Walter Moll

Many exotic metallic systems have a resistivity that varies linearly with temperature, and the physics behind this is thought to be connected to high-temperature superconductivity in the cuprates and iron pnictides1,2,3,4,5,6,7,8,9. Although this phenomeno ...

Spice-compatible modeling of high injection and propagation of minority carriers in the substrate of Smart Power ICs

Maher Kayal, Jean-Michel Sallese, Camillo Stefanucci, Pietro Buccella

Classical substrate noise analysis considers the silicon resistivity of an integrated circuit only as doping dependent besides neglecting diffusion currents as well. In power circuits minority carriers are injected into the substrate and propagate by drift ...

A nanoscale gigahertz source realized with Josephson scanning tunneling microscopy

Klaus Kern, Markus Etzkorn, Matthias Alexander Eltschka, Maximilian Assig

Using the AC Josephson effect in the superconductor-vacuum-superconductor tunnel junction of a scanning tunneling microscope (STM), we demonstrate the generation of GHz radiation. With the macroscopic STM tip acting as a lambda/4-monopole antenna, we first ...

Ultra Fine-Pitch TSV Technology for Ultra-Dense High-Q RF Inductors

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia, Wolfgang Amadeus Vitale, Josef Weber

We demonstrate that fine-pitch TSV technology can be exploited to fabricate micro-inductors on high resistivity substrate, with record-high inductance per area and preserving their performance at GHz frequencies. We report an extensive experimental study o ...

Quantitative Extraction of Equivalent Lumped Circuit Elements for Complex Plasmonic Nanostructures

Olivier Martin, Christian Santschi, Banafsheh Abasahl

We establish a general method to bridge the gap between full-field electromagnetic calculations and equivalent lumped circuit elements to describe the optical response of plasmonic nanostnictures. The exact value of each lumped element is extracted from on ...

Field enhancement and saturation of milimeter waves inside a metallic nanogap

Hoài-Minh Nguyên

This paper investigates the millimeter electromagnetic waves passing through a metal nanogap. Based upon the study of a perfect electrical conductor model, we show that the electric field enhancement inside the gap saturates as the gap size approaches zero ...

MRS glucose mapping and PET joining forces: Re-evaluation of the lumped constant in the rat brain under isoflurane anaesthesia

Rolf Gruetter, Hongxia Lei, João Miguel das Neves Duarte, Malte Alf

Although numerous positron emission tomography (PET) studies with ((8) F-fluoro-deoxyglucose) FDG have reported quantitative results on cerebral glucose kinetics and consumption, there is a large variation between the absolute values found in the literatur ...

Dictionary learning over large distributed models via dual-ADMM strategies

Ali H. Sayed

We consider the problem of dictionary learning over large scale models, where the model parameters are distributed over a multi-agent network. We demonstrate that the dual optimization problem for inference is better conditioned than the primal problem and ...

Optimization Strategy of Numerical Simulations Applied to EPFL Substrate Model

Maher Kayal, Jean-Michel Sallese, Camillo Stefanucci, Pietro Buccella

A new methodology for modeling minority carriers diffusion in Smart Power ICs substrate using standard circuit simulators has been proposed by EPFL. For this purpose, a parasitic substrate network consisting of lumped elements is extracted from the circuit ...
