Commercialized bulk constantan with a low dimensionless figure of merit and its film fabricated by electroplating were prepared to demonstrate the feasibility of impedance spectroscopy for estimating thermoelectric parameters. From the frequency dependence of the impedance, the resistivity and dimensionless figure of merit were directly estimated as 5.3 × 10 −7 Ωm and 0.026 for the bulk and 3.8 × 10 −7 Ωm and 0.0098 for the film at room temperature (302 K), respectively. We concluded that impedance spectroscopy is a suitable technique for estimating the thermoelectric parameters of any material with an apparent Seebeck coefficient.

使用阻抗谱估计的常数的无量纲品质因数

制备了具有低无量纲品质因数的商品化大体积康斯坦丁及其通过电镀制备的薄膜，以证明阻抗光谱法估计热电参数的可行性。根据阻抗的频率依赖性，在室温（302 K）下，薄膜的电阻率和无量纲品质因数直接估计为5.3×10 -7Ωm和0.026（体积）和3.8×10 -7Ωm和0.0098。分别。我们得出的结论是，阻抗谱法是一种适用的技术，可用于估算具有明显塞贝克系数的任何材料的热电参数。
