Influence of the injection current sweep rate on the polarization switching of vertical-cavity surface-emitting lasers
(American Institute of Physics, 2006-12)
We study the polarization switching of vertical-cavity surface-emitting lasers based on simulations of the spin-flip model. We show that the switching point depends on the ramp signal used to scan the injected current. ...
Stochastic Current-Induced Magnetization Switching in a Single Semiconducting Ferromagnetic Layer
(American Physical Society, 2014-01-14)
We show experimental evidence of magnetization switching in a single (Ga,Mn)(As,P) semiconducting ferromagnetic layer, attributed to a strong reduction of the magnetization and the anisotropy due to current injection. The ...
Optimized Switching Sequence for Multiphase Power Converters Under Inductance Mismatch
(Institute of Electrical and Electronics Engineers, 2017-03)
Multiphase power converters allow to reduce semiconductor stress and to improve total ripple characteristics, when compared to a single-phase converter. Semiconductor stress is reduced by dividing the total current among ...
Evaluation of DC-AC single-phase solid-state transformers
(Institute of Electrical and Electronics Engineers, 2019-11-02)
This work presents an evaluation of three topologies of DC-AC single-phase solid-state transformers, for applications in electric microgrids. The main features of these topologies are galvanic isolation, capability to ...
Multistructure Power Converter With H-Bridge Series Regulator Suitable for High-Current High-Precision-Pulsed Current Source
(Institute of Electrical and Electronics Engineers, 2014-12)
This study presents a novel multistructure power converter capable of generating high current pulses with short rise and fall times, and high precision in the flat-top. The proposed topology is based on the use of three ...

Study on the Connection Between the Set Transient in RRAMs and the Progressive Breakdown of Thin Oxides
(Institute of Electrical and Electronics Engineers, 2019-08)
In this paper, the transition rate (TR) from the high-resistance state to the low-resistance state of a HfO2-based resistive random access memory (RRAM) is investigated. The TR is statistically characterized by applying ...
