Oxide-based resistive switching devices have been shown be promising candidate realize functions synapse. However, intrinsic variation...
The resistive random access memory (RRAM) crossbar array has been extensively studied as one of the most promising candidates for future high-density nonvolatile technology. However, some problems caused by circuit and device interaction, such sneak leakage paths, result in limited size large power consumption, which degrade performance significantly. Thus, analysis on interaction issue is imperative. In this paper, a simulation method developed to investigate critical issues correlated with...

Lithium‐sulfur (Li‐S) batteries are promising energy storage devices due to their high theoretical density and cost‐effectiveness. However, the shuttle effect of polysulfides during charging discharging processes leads a rapid decline in capacity, thereby restricting application storage. The separator, crucial component Li‐S batteries, facilitates transport Li+ ions. large pores present on surface separator insufficient prevent shuttling polysulfides. This paper proposes straightforward...
