Study of Resistive Switching Dynamics and Memory States Equilibria in Analog Filamentary Conductive‐Metal‐Oxide/HfOx ReRAM via Compact Modeling

Advanced Electronic Materials, EarlyView.
A physics‐based compact model for Conductive‐Metal‐Oxide/HfOx ReRAM, accounting for ion dynamics, electronic conduction, and thermal effects, is presented. Accurate and versatile simulations of analog non‐volatile conductance modulation and memory state stabilization enable reliable circuit‐level studies, advancing the optimization of neuromorphic and ...

A General and Efficient Framework for the Rapid Design of Miniaturized, Wideband, and High‐Bit RIS

Advanced Electronic Materials, EarlyView.
A general and efficient framework is proposed for the rapid design of high‐performance reconfigurable intelligent surfaces (RISs). This framework integrates advanced antenna design techniques and incorporates various load types, quantities, and values to achieve the design of high‐performance RISs.

Traps, Tail States and Their Consequences on the Open‐circuit Voltage in Organic Solar Cells

Advanced Energy Materials, EarlyView.
It is found that the light‐intensity dependent low‐temperature roll‐off of open‐circuit voltage in organic solar cells is explained by the intrinsic disorder in these devices, which can be either described by the full Gaussian density of states or approximated by a two‐level system, which allows for a more intuitive interpretation.

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

Advanced Energy Materials, EarlyView.
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

Impact of Trap Depth on the Steady‐State and Transient Photoluminescence in Halide Perovskite Films

Advanced Energy Materials, EarlyView.
The presence of shallow traps in halide perovskites is frequently postulated by density functional theory calculations. This review studies the implications of recombination‐active shallow traps on steady‐state and transient recombination kinetics. How to identify shallow traps and how the depth of the traps and their density are reflected in different
