Grain-boundary engineering driven high-performance Bi–Sb–Te bulk thermoelectric materials fabricated by gas atomization and hot extrusion

Grain-boundary engineering is an effective strategy for enhancing the thermoelectric properties of Bi2Te3-based materials. Through modulating grain-boundary characteristics via a gas atomization (GA)/hot extrusion (HE) fabrication technology, a high-performance bulk (Bi0.2Sb0.8)2Te3 material with a...
