combining texturing with nanostructuring provides a balance between TE and mechanical performance in n-type Bi2Te3-based materials. Low/midfrequency phonons are most likely to be scattered by nanoscale defects, thus significantly reducing the lattice thermal conductivity. High efficiencyTEdevices are needed to meet the increasing demand for electronic cooling applications, which is driving current research activities devoted to performance enhancement for the n-type materials. Creating textured microstructure in favor of carrier transport, together with optimized nanostructure strengthening phonon scattering, could be an effective strategy. Additionally, the n-type base composition could be further tuned to raise the ZT values around room temperature, not by increasing the peak temperature.
