Enhancing Thermoelectric Performance in L-DED-Printed p-Type Bi2Te3 by Synergistic Lattice Planarization and Defect Engineering.
While laser 3D printing offers unique advantages for fabricating complex architectures, its broader application is hindered by the stringent requirements for high-quality powder precursors and the inferior thermoelectric properties of the printed bulk materials. Herein, irregularly shaped p-type Bi0.5Sb1.5Te3 powders w...
