Ultrafast Multilevel Switching and Synaptic Behavior in a Planar Quantum Topological Memristor

Advanced Science, EarlyView.
Dry‐transferred Bi2Te3 layers enable a planar quantum topological memristor framework. In‐plane topological surface states facilitate ultrafast & low‐power operations. Coexisting analog and digital modes support current‐controlled multilevel states. PQTM exhibits 105 s retention, 103 cycles endurance, and reproducibility across 24 devices.

Thermoelectric Property Mapping for High‐Performance Integrated MgAgSb‐MgCuSb System

Advanced Science, EarlyView.
From the property mapping of the MgAgSb–MgCuSb system, both thermoelectric materials and corresponding interface materials are optimized: Ag‐rich compositions provide higher PF and zT, whereas Cu‐rich side yields superior transport properties and low contact resistance.

Embedded Direct‐Written Organic Micro‐TEGs for High‐Efficiency Skin‐Heat Harvesting

Advanced Electronic Materials, EarlyView.
A finite‐element–guided design of direct‐written organic micro‐thermoelectric generators is presented for efficient skin‐heat harvesting. Embedding PEDOT:PSS/PBFDO thermoelectric legs within flexible substrates suppresses interfacial heat losses and enhances vertical heat flow.

Advances in Thermoelectric Thin Films Grown by Atomic Layer Deposition: A Critical Review of Performance and Challenges

Advanced Energy Materials, EarlyView.
This review highlights the use of atomic layer deposition (ALD) for fabricating thermoelectric thin films with atomic‐scale control. Four material classes—chalcogenides, doped oxides, ternary oxides, and multilayered structures—are compared in terms of growth dynamics, structure–property relationships, and thermoelectric performance. The precise tuning
