Abstract
Herein we report the optimized processing conditions of hot extrusion for fabricating an n-type Bi₂Te_2.7Se_0.3 thermoelectric compound, with high electronic transport properties as well as improved mechanical reliability. We fabricated a Bi₂Te_2.7Se_0.3 extrudate that was 3.8 mm in diameter and 700 mm in length by controlling the processing parameters of..... More
