Silicon Nitride Resistive Memories

Advanced Electronic Materials, EarlyView.
Amorphous SiNx is an attractive resistance switching material for ReRAM applications due to its physicochemical properties, such as humidity resistance, low oxygen diffusivity, and is used as a metal diffusion blocker. By modifying the ratio between N and Si atoms, the microstructure of the SiNx is affected, rendering it possible to change the ...

Side‐Chain Branching Dictates the σ–S Coupling in Conjugated Polymer Thermoelectrics

Advanced Electronic Materials, EarlyView.
The correlation between conductivity and Seebeck coefficient has been extensively studied in numerous works. Nevertheless, its association with side chains has not been thoroughly explored. In this work, we found that the distance between the branching points of side chains and the molecular backbones has a significant effect on thermoelectric ...

Thermal Conductivity Across the Nonpolar‐Polar Phase Transition in Incipient Ferroelectric KTaO3

Advanced Electronic Materials, EarlyView.
Phonon dispersion of the cubic nonpolar ground‐state and a ferroelectric tetragonal phase, stabilized by a compressive strain of 2%. ABSTRACT The manipulation of the lattice of polar materials via external electric fields is an effective way to dynamically control the heat flux, accessing different thermal conductivity, κ${\bm \kappa }$, states ...

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

Advanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...
