Carrier-phonon decoupling via annealing enhances thermoelectric performance of Bi2(Te,Se)3

Xinxiu Cheng, Liqing Xu, Zhibin Gao +4

Thermoelectric cooling based on the Peltier effect requires high-performance materials near room temperature. In this work, Bi2Te2.6Se0.4 synthesized by melting-hot pressing follow…

Phase transition and polar cluster behavior above Curie temperature in ferroelectric BaTi $_{0.8}$ Zr $_{0.2}$ O $_{3}$

Oktay Aktas, Francisco Javier Romero, Zhengwang He +5

We study the phase transition behavior of the ferroelectric BaTi $_{0.8}$ Zr $_{0.2}$ O $_{3}$ in the paraelectric region. The temperature dependencies of thermal, polar, elastic and diel…
