Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

Advanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...

Effects of Thermal and Lévy Noise Sources on the Switching Current Distributions of a Josephson Junction

, 2021
We discuss the combined effect of Gaussian and α-stable Lévy noise sources on the switching current distribution of a short tunnel Josephson junction, while an external bias current flowing through the junction is linearly swept. At a fixed temperature,

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor

Advanced Functional Materials, EarlyView.
Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

Sneaking Operation Modes in Zero-Current-Switching Converter

The Open Electrical & Electronic Engineering Journal, 2015
This paper reports the occurrence of some abnormal operational modes in soft-switching converters. By constructing a Boolean matrix based on the states of the switching components, some unexpected topological states are identified. Consequently, these states excite the abnormal or sneaking operational modes as referred.
