介绍了一种新的一维纳米线阵列结构温差电材料热电性能测试技术。该技术创造性地采用了液流加热以及异地测温的新方法,成功地解决了对微米厚度的一维纳米线阵列结构热电材料试样两侧均匀加热并保持两侧的温差恒定,以及微米厚度的试样两侧测温的难题。依据这一原理建立了一维纳米线阵列结构热电材料性能测试系统。实验表明,该系统性能稳定,精度高,可胜任一维纳米线阵列结构热电材料的性能测试。

A new measuring technology for thermoelectric performance of the thermoelectric material with nanowire array structure (NWAS) was introduced. The liquid heating and allopatric temperaturemeasuring method were adopted in the technology in order to heat the two sides of specimen with NWAS evenly and keep the temperature difference constant, and to measure the temperature of the two sides of the specimen. The measuring system for thermoelectric performance of the thermoelectric material with NWAS was developed according to the principle. The experimental results show that the system, which has stable performance and high precision, is qualified to measure the thermoelectric performance of any thermoelectric material with NWAS.
