300- 600 K简单可逆梯度塞贝克系数测量系统
Simple, Reversible Gradient Seebeck Coefficient Measurement System for 300-600K
摘要：
自行研制了一套塞贝克系数测量系统，可在300-600 K的温度范围内测量样品在大温差下的热电动势（塞贝克系数）。与大多数已报道的仪器设计不同，该系统没有热壁室，因此更接近实时热电应用条件。该系统由两个黄铜块支撑的加热器组成。这些加热器通过银帽放置在样品的两侧，从而允许单独的温度控制。在样品上施加可逆的温度梯度，并以准静态直流模式进行测量。因此，获得更精确的塞贝克系数测量。
英文摘要：
An in-house Seebeck coefficient measurement system has been developed which can measure the thermoemf (Seebeck coefficient) of the sample, under large temperature difference, in the temperature range 300-600 K. Unlike majority of reported instrumental designs, the system does not have a hot walled chamber and hence is much closer to real time thermoelectric applications conditions. The system consists of two brass blocks supported heaters. These heaters are placed on either side of the sample through silver caps, thus allows individual temperature control. A reversible temperature gradient is applied across the sample and the measurement is carried out in quasi-static direct current mode. Hence, a more accurate Seebeck coefficient measurement is obtained.
