Suppressing the donor-like effect via fast extrusion engineering for high thermoelectric performance of polycrystalline Bi2Te2.79Se0.21

Suppressing the donor-like effect via fast extrusion engineering for high thermoelectric performance of polycrystalline Bi2Te2.79Se0.21

Bi2Te3-based alloys are the most mature commercial thermoelectric (TE) materials for the cooling application near room temperature. However, the poor mechanical properties of the commercial zone melting (ZM) ingot severely limits the further application. Meanwhile, due to the donor-like effect, the...
