摘要/Abstract

摘要：

Bi₂Te₃基化合物是目前得到广泛商业应用的热电材料, 其湿热稳定性直接影响着热电器件的服役可靠性。本工作探究了商用n型Bi₂Se_0.21Te_2.79和p型Bi_0.4Sb_1.6Te₃热电材料存储于85 ℃, 85% RH（相对湿度）湿热环境600 h期间的降解行为。在湿热处理600 h后, n型Bi₂Se_0.21Te_2.79和p型Bi_0.4Sb_1.6Te₃材料表面均被氧化, 反应过程分别为Bi₂Te₃+O₂→Bi₂O₃+TeO₂和Bi₂Te₃+Sb₂Te₃+O₂→Bi₂O₃+Sb₂O₃+TeO₂。氧化过程在材料内部产生了纳米级孔洞, 甚至微裂纹, 导致材料的电、热性能全面劣化。在室温时, n型Bi₂Se_0.21Te_2.79材料的电导率从存储前的9.45×10⁴ S·m^-1显著下降到7.79×10⁴ S·m^-1, ZT则从0.97下降至0.79; p型Bi_0.4Sb_1.6Te₃材料的Seebeck系数从243 μV·K^-1明显减小至220 μV·K^-1, ZT则从1.24降低到0.97。综上所述, Bi₂Te₃基热电材料的湿热稳定性极差, 微型热电器件在服役过程中需要进行严格封装, 以阻止热电材料自身与环境中的水汽、空气发生复杂的氧化还原反应。

Abstract:

Bi₂Te₃-based thermoelectric (TE) materials have already been commercialized, of which the hygrothermal stability has a direct impact on the service reliability of TE devices, but is still confronted many challenges. This work investigated the degradation behavior of commercial n-type Bi₂Se_0.21Te_2.79 and p-type Bi_0.4Sb_1.6Te₃ TE materials during storage in 85 ℃, 85% RH hygrothermal environment for 600 h. The surfaces of n-type Bi₂Se_0.21Te_2.79 and p-type Bi_0.4Sb_1.6Te₃ TE materials were oxidized with reaction process of Bi₂Te₃+O₂→Bi₂O₃+TeO₂ and Bi₂Te₃+Sb₂Te₃+O₂→Bi₂O₃+Sb₂O₃+TeO₂, respectively. The oxidation process creates nanoscale holes and even microcracks inside the material, which leads to an overall deterioration of the electrical and thermal properties. At room temperature, the electrical conductivity of the n-type Bi₂Se_0.21Te_2.79 material drops from 9.45×10⁴ S·m^-1 to 7.79×10⁴ S·m^-1 after exposure, and ZT decreases from 0.97 to 0.79, while Seebeck coefficient of the p-type Bi_0.4Sb_1.6Te₃ material declines from 243 μV·K^-1to 220 μV·K^-1, correspondingly, ZT decreases from 1.24 to 0.97. In conclusion, Bi₂Te₃-based TE materials have extremely poor hygrothermal stability, and their corresponding micro-TE devices need to be strictly encapsulated in service to prevent complex redox reactions between the TE materials themselves and the environmental water vapor and air.
