Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

open access: yesAdvanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

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

open access: yesAdvanced 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.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Fermi resonance and Raman intensities of carbon disulphide

open access: yes, 1984
The gas‐phase Raman spectrum of CS2 has been recorded and analysed in the region of the ν1 : 2ν2 Fermi resonance. The absolute differential Raman scattering cross‐sections and depolarization ratios of the observed vibrational transitions are ...

Identification Characteristics of Natural and Synthetic Amethyst by Infrared and Polarized Raman Spectroscopy

open access: yesYankuang ceshi, 2019
BACKGROUND The identification of natural and synthetic amethyst is still a challenge for gemological laboratories either at home or abroad. Previous studies focus on twinning, color band, inclusions and the infrared spectrum.

Raman scattering enhancement of dielectric microspheres on silicon nitride film

open access: yesScientific Reports, 2022
Circulating light in the total internal reflection within dielectric spheres or disks is called the whispering gallery mode (WGM), which by itself is highly sensitive to its surface and capable of detecting viruses and single atomic ions.

Spatially Regulated Lithium Plating via Li2O‐Rich Interphase Enables Durable Fast‐Charging Hybrid Lithium Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A Li2O‐rich solid electrolyte interphase (SEI) is engineered on graphite through a propylene carbonate‐based electrolyte to spatially regulate Li plating. The homogeneous interphase lowers Li nucleation barriers, promotes conformal Li deposition around graphite particles, and suppresses dendritic accumulation, enabling durable hybrid Li‐ion/Li‐metal ...

The Raman spectrum of rutile

open access: yes, 1962
The Raman spectrum of rutile has been investigated both at room temperature and at the temperature of liquid air. The Raman lines which, at room temperature are quite wide, are observed to sharpen greatly at the low temperature.
