In this paper, we report a fully automated experimental apparatus for measuring Seebeck coefficient and electrical resistivity of a sample simultaneously in a temperature range of 100-600 K. The Seebeck coefficient is measured using a quasi-steady temperature differential method in which two ceramic heaters are employed to alternately heat the sample. The sample holder is designed to reduce temperature disturbance on its base during a measurement cycle. To demonstrate the accuracy and reliability of the experimental setup, we have performed tests on reference materials including constantan and platinum.
在本文中，我们报告了一种全自动实验装置，用于在100 - 600 K的温度范围内同时测量样品的塞贝克系数和电阻率。塞贝克系数采用准稳态温差法测量，其中使用两个陶瓷加热器交替加热样品。样品架的设计旨在减少测量周期内其基座上的温度干扰。为了证明实验装置的准确性和可靠性，我们对包括康铜和铂在内的参考材料进行了测试。
