Metallic grain boundary resistance in the high temperature thermoelectric La3Te4
Journal of MateriomicsElectrical resistance from grain boundaries limits the thermoelectric performance of many materials. Boundary resistance is typically observed as an increase in resistivity at low temperature that decays exponentially with temperature like the ...

Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors
Advanced Materials, EarlyView.This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

Moisture-gradient-enhanced ionic thermoelectrics
Nature CommunicationsIonic thermoelectrics (i-TEs) demonstrate immense application potential in such fields as wearables and low-grade energy harvesting. Though adequate moisture absorption is required to facilitate ion dissociation in i-TEs, the impact of moisture gradient ...

Tunable p-p Interactions Along Linear Chains Control Metavalent Bonding in Chalcogenide Heterostructures. [PDF]
Adv Sci (Weinh)Substitution of Sr at the Pb site within an atomic plane of PbTe perturbs the p–p hopping network. Since Sr does not support the p–p interaction key to metavalent bonding along (‐Pb‐Te‐) chains, long‐range electronic charge transfer in response to displacement of Pb is stalked at the Sr site.
