Dual-Functional Modulation of Electronic Structure and Lattice Strain Toward Decoupled Thermoelectric Performance and Mechanical Enhancement in Na-Doped In2O3 Used for Welding Robot
Wide-bandgap indium-oxide thermoelectric materials face a strong electrical–thermal transport trade-off and low structural reliability, limiting their thermoelectric efficiency and practical deployment on welding robots. To overcome these bottlenecks, gradient Na-doped In2O3 ceramics are fabricated by mechanical alloyi...
