High‐Mobility and Low‐Voltage Top‐Gate Transistors Comprising an InSnO–InSnWO Channel Layer and a Polymethyl Methacrylate Dielectric Layer

Advanced Materials Interfaces, EarlyView.
The top‐gate thin film transistors (TFTs) combining the advantages of both the inorganic InSnWO channel layer and the organic polymethyl methacrylate dielectric layer were prepared. The optimized TFTs exhibit excellent performance, including a high mobility (> 60 cm2 V−1 s−1), a low threshold voltage (< 0.50 V; positive value), and robust stabilities ...

Additive Manufacturing of Ni‐Based Thermoelectric Materials for Waste Heat Recovery

Advanced Materials Technologies, EarlyView.
Thermoelectric generators convert waste heat into electricity but are constrained by conventional fabrication. Here, laser powder bed fusion enables direct printing of customised n‐type Cu60Ni40 and p‐type Ni90Cr10 legs. The assembled module achieves 0.8% efficiency at ΔT = 419 K, demonstrating scalable additive manufacturing of eco‐friendly, design ...

Spin Hall effect investigated by spin Hall magnetoresistance in Pt100−xAux/CoFeB systems

AIP Advances, 2019
We studied spin Hall effect (SHE) in Pt100-xAux with various Au compositions x for Pt-Au/CoFeB systems by means of spin Hall magnetoresistance (SMR). We synthesized low resistive, flat, and highly (111)-textured Pt-Au alloy films by sputtering using low ...

High‐Performance Ternary Organic Solar Cells via Isomeric Engineering of Nonfullerene Guest Acceptors

Advanced Science, EarlyView.
Two isomeric nonfullerene acceptors, BTP‐γ‐Br and BTP‐δ‐Br, were designed to investigate their effects on the optoelectronic properties and photovoltaic performance of ternary blends. Incorporating BTP‐γ‐Br into the D18:N3 binary system can enhance film crystallinity and suppress charge recombination, achieving a high PCE of 19.2% and a certified JSC ...
