Decoupling Electron and Phonon Transport in 3D‐Printed Bismuth Telluride via Synergistic Compositional Co‐Enrichment

Decoupling electronic and phononic transport requires nanoscale control over scattering landscapes. Here, we show that direct ink writing generates a hierarchical nanoarchitecture in Bi2Te3, which comprises nanopores (10‐150 nm), amorphous‐crystalline nanointerfaces, and dense grain boundary networks that suppress latt...
