Extrusion-printed La 3-x Te 4 legs with interlocking Ni electrode for high-temperature thermoelectric devices

Nature Communications, Published online: 05 May 2026; doi:10.1038/s41467-026-72616-0 Thermoelectric devices require more scalable, cost-effective methods of manufacturing. Here, the authors ink print high-performing La3-xTe4 legs with interlocked electrodes and evaluate their interfaces with creep property measurements and modeling.
