Scalable colloidal synthesis of Bi₂Te_2.7Se_0.3 plate-like particles give access to a high-performing n-type thermoelectric material for low temperature application.

ABSTRACT: Colloidal synthesis is harnessed for the gram-scale preparation of hexagonal-shaped plate-like Bi₂Te_2.7Se_0.3 particles, yielding nearly 5 g of the product in one experiment. The resultant textured particles are highly crystalline, phase-pure, chemically uniform, and can serve as a starting material for the preparation of bulk thermoelectrics for room temperature applications. The consolidation occurs via spark plasma sintering, which affords nanostructured n-type Bi₂Te_2.7Se_0.3 material exhibiting a high figure of merit ZT ≈ 1 at 373 K with an average ZT ≈ 0.93 (300-473 K). Our experimental and theoretical studies indicate that the high thermoelectric performance is attributed to a favorable combination o
