Interplay of Backbone Conformation, Morphology and Thermoelectric Properties of Benzodifuranone‐Isatin Acceptor Polymers

open access: yesAdvanced Electronic Materials, EarlyView.
Modification of polymer backbone via halogenation and comonomer selection leads to conjugated backbones of different stereoelectronic properties, thin film morphologies, and electrical characteristics. The interplay of conformational isomerism, coplanarity, backbone curvature, backbone orientation, and ordering in thin films, electrical conductivity ...

Lattice Dynamics Across the High‐Pressure Phase Transition in CrTe

open access: yesAdvanced Electronic Materials, EarlyView.
ABSTRACT High‐pressure physics provides a powerful means of tuning interatomic interactions, enabling the discovery of novel structural and physical phenomena in materials. Chromium telluride, a transition metal chalcogenide, is particularly responsive to such external stimuli, exhibiting a broad spectrum of pressure‐, temperature‐, and stoichiometry ...

Lattice Dynamics of Rutile Germanium Dioxide (r‐GeO2)

open access: yesAdvanced Electronic Materials, EarlyView.
The rutile polymorph of GeO2 is a promising ultra‐wide bandgap material, but key properties for its technological exploitation remain poorly understood. Using polarization angle‐resolved Raman spectroscopy, we resolve long‐standing uncertainties in the energies of Raman‐active phonons and extract relative Raman tensor elements.

Stretchable Energy Storage with Eutectic Gallium Indium Alloy

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A highly stretchable liquid metal‐based electrode is developed via a one‐step process, retaining conductivity and capacitance after mechanical deformation up to 900% strain. The stretchable all‐solid‐state device provides a areal energy density of 43 µWh cm⁻2 after 150% strain.

Intrinsic Mechanical Parameters and their Characterization in Solid‐State Lithium Batteries

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
This review focuses on the intrinsic mechanical parameters and their associated characterization in solid‐state batteries. The physical significance of mechanics parameters is introduced with exhaustive classifications by elastic, plastic deformations and fracture in bulk, adhesion, friction at interfaces, and mechanical fatigue in cells ...
