Balancing Effective Mass and Carrier Mobility via Ga‐Induced Multi‐Band Valley Engineering in GeTe Thermoelectrics

open access: yesAdvanced Science, EarlyView.
Ga doping drives simultaneous convergence of three valence bands and formation of a midgap band in Ge0.94Bi0.06Te, enhancing the Seebeck coefficient without sacrificing carrier mobility. Lattice vibration disorder and multi‐scale defect engineering suppress lattice thermal conductivity, delivering a ZT exceeding 2.1 and enabling efficient lead‐free ...

Volcano‐Inspired Dual‐Carbon Network Aerogel for High‐Performance Solar Evaporation With Edge‐Directed Salt Crystallization and Recovery

open access: yesAdvanced Science, EarlyView.
A volcano‐inspired dual‐carbon aerogel featuring hierarchical conduits and an outer carbon‐fiber shell directs rapid water transport, confines heat, and enables directional salt migration. Radial temperature gradients in the conical structure trigger Marangoni‐driven edge‐localized salt crystallization while maintaining an unobstructed photothermal ...

Controlled Moderate Interfacial Reaction Facilitates High‐Strength Low‐Resistivity Barrier Layer for Half‐Heusler Thermoelectrics

open access: yesAdvanced Science, EarlyView.
The barrier layer is designed comprehensively by thermal expansion coefficient and interfacial reaction energy to yield a controlled interfacial reaction. Ultimately, the Co25Fe50Ni25/half‐Heusler joint simultaneously achieves low contact resistivity and high bonding strength.

Delocalized Charge Transport in Thermoelectric Composites of Semiconducting Carbon Nanotubes Wrapped with a P‐Type Polymer

open access: yesAdvanced Electronic Materials, EarlyView.
Composites made of semiconducting carbon nanotubes and p‐type polymers, when adequately doped with molecular dopants, can exhibit highly delocalized charge carrier transport, showing high thermoelectric performances. The efficient charge delocalization is enabled by the reduced coulombic binding energy at high carrier concentration and the small ...

Computational Microscopy of Spatial Dopant Distribution in Conjugated Polymer

open access: yesAdvanced Electronic Materials, EarlyView.
The study employed molecular dynamics simulations to investigate the distribution of dopants in conjugated polymers. The simulations revealed that dopants are randomly distributed without forming clusters, contrasting with experimental findings of dopant clustering.

Improving the Thermoelectric Properties of Conjugated Polymer Thin Films by Dip Coating – but not through Alignment

open access: yesAdvanced Electronic Materials, EarlyView.
The study demonstrates that dip coating at lower speeds significantly enhances the thermoelectric performance of P3HT by improving electrical conductivity. Contrary to expectations, this improvement is seemingly not due to polymer alignment but rather to better structural order achieved during slower solvent evaporation at lower dip coating speeds ...
