Multi-Variable High-Frequency Input-Admittance of Grid-Connected Converters: Modeling, Validation and Implications on Stability

Drazen Dujic, Francisco Daniel Freijedo Fernández, Marc Ferrer Duran

Modern grids are facing a massive integration of power electronics devices, usually associated to instability issues. In order to assess the likelihood and severity of harmonic instability in the high frequency region, this work develops a multi-variable i ...

Ultrathin Junctionless Nanowire FET Model, Including 2-D Quantum Confinements

Farzan Jazaeri

In this paper, we develop an explicit model to predict the dc electrical behavior in ultrathin surrounding gate junctionless (JL) nanowire field-effect transistors (FETs). The proposed model considers 2-D electrical and geometrical confinements of carrier ...

Understanding ultrasound neuromodulation using a computationally efficient and interpretable model of intramembrane cavitation

Silvestro Micera, Esra Neufeld, Théo Lemaire

Objective. Low-intensity focused ultrasound stimulation (LIFUS) emerges as an attracting technology for noninvasive modulation of neural circuits, yet the underlying action mechanisms remain unclear. The neuronal intramembrane cavitation excitation (NICE) ...

Reduction of a Cone-Shaped Terrain Grounding Resistance by Remote Grounding

Marcos Rubinstein, Antonio Sunjerga

Tall structures such as wind turbines and mobile phone base stations are often installed in remote and hilly locations to gain more power or to have line of sight to end users. Those locations are usually very rocky and characterized by a low-conductivity ...

The influence of the incommensurately modulated structure on the physical properties of Fe1.35Ge

László Forró, Alla Arakcheeva, Helmuth Berger, Philip Pattison, Krunoslav Prsa, Andrea Pisoni, Sergiy Katrych, Jacim Jacimovic

Single crystal growth by chemical vapour transport has resulted samples with Fe1.35Ge stoichiometry. Structural study has shown that the large number of vacancies introduces an incommensuately modulated structure. The electrical resistivity is in the 200 m ...

Contact Resistivity of the p-Type Amorphous Silicon Hole Contact in Silicon Heterojunction Solar Cells

Mathieu Gérard Boccard

In silicon heterojunction solar cells made with high-lifetime wafers, resistive losses in the contacts dominate the total electrical power loss. Moreover, it is widely believed that the hole contact stack—a-Si:H(i)/a-Si:H(p)/ITO/Ag—is responsible for more ...

A novel microfabrication platform for hybrid multilayer MEMS

Nahid Hosseini

In Atomic force microscopy (AFM), the tip-sample interaction force can be measured through two primary detection techniques: optical beam detection (OBD) and electrical (self-sensing) readout. Compared to the optical method, the convenience of the self-sen ...

Persistent antiferromagnetic order in heavily overdoped Ca1-xLaxFeAs2

László Forró, Henrik Moodysson Rønnow, Ivica Zivkovic, Philip Johannes Walter Moll, Ana Akrap, Sergiy Katrych, Maja Deborah Bachmann, Edoardo Martino

In the Ca1-xLaxFeAs2 (1 1 2) family of pnictide superconductors, we have investigated a highly overdoped composition (x = 0.56), prepared by a high-pressure, high-temperature synthesis. Magnetic measurements show an antiferromagnetic transition at T-N = 12 ...

Optimal Placement of Inertia and Primary Control: A Matrix Perturbation Theory Approach

Philippe René Joseph Jacquod

The increasing penetration of new renewable sources of electrical energy reduces the overall mechanical inertia available in power grids. This raises a number of issues regarding grid stability over short to medium time scales. A number of approaches have ...

The Effect of Yttrium Addition on the Microstructures and Electrical Properties of CuMn Alloy Thin Films

Ho-Yun Lee

In this study, we fabricated thin-film resistors using CuMn and yttrium targets by DC/RF magnetron cosputtering. CuMnY-resistive thin films were deposited onto glass and Al2O3 substrates. The electrical properties and microstructures of CuMn alloy films wi ...
