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

Advanced 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.

hybridModels: An R Package for the Stochastic Simulation of Disease Spreading in Dynamic Networks

Journal of Statistical Software, 2020
Disease spreading simulations are traditionally performed using coupled differential equations. However, in the setting of metapopulations, most of the solutions provided by this method do not account for the dynamic topography of subpopulations ...

Simulation of a stochastic vortex tangle [PDF]

Low Temperature Physics, 2003
We present the results of a simulation of the chaotic dynamics of quantized vortices in the bulk of superfluid He II. The evolution of vortex lines is calculated on the basis of the Biot—Savart law. The dissipative effects arising from the interaction with the normal component or/and from relaxation of the order parameter are taken into account ...

Mesoscale Domain Evolution Mechanism during Alternating Current (AC) Poling of Relaxor Ferroelectrics

Advanced Functional Materials, EarlyView.
Ferroelectric domain variants that are energetically equivalent are expected to remain preserved during polarization reversal. However, phase‐field simulations reveal that inclined domain walls in relaxor ferroelectrics can undergo irreversible elimination during alternating current poling through a proximity effect driven by long‐range elastic ...
