Texture Engineering to Boost the Thermoelectric Properties

Thermoelectrics for nuclear fusion reactors: opportunities and challenges

“…However, it may be possible for a polycrystalline material to recover some of its anisotropic properties as a single crystal through texture engineering techniques. 155 Using the n-type Bi 2 Te 3− x Se x material as an example, nanoplates were synthesized by colloidal synthesis techniques, followed by adding excess Te and sintering them under a uniaxial pressure beyond the melting point of Te. The molten excess Te not only functioned as a liquid sintering aid to ease the movement and stacking of the nanoplates, but also as a solvent that dissolves and reprecipitates Bi 2 Te 3− x Se x , causing them to recrystallize under the uniaxial pressure and grow laterally.…”
