西元1911年，科學家Heike Kamerlingh Onnes在低溫4.2K時發現了汞的超導性質。超導材料具有零電阻、反磁性的特點，且可應用的層面相當廣泛，例如核磁共振（nuclear magnetic resonance, NMR）。超導磁浮列車所用的超強磁鐵……等。 本研究主要探討釔鋇銅氧材料的熱電性質，我們研究的溫度範圍區間為80K~320K，討論超導體於此溫度區間的電阻率、Seebeck、以及熱傳導的變化，並且嚐試以現有理論去解釋其變化趨勢，探討不同溫度對於YBCO的熱電性值影響。 ;In 1911, the scientist Heike Kamerlingh Onnes found mercury superconductivity at a low temperature of 4.2K. Superconducting materials have zero resistance, anti-magnetic characteristics, and can be applied to a wide range of levels, such as nuclear magnetic resonance (nuclear magnetic resonance, NMR). In our article, we perform performed a study of temperature dependence of thermal conductivity, Seebeck coefficient, and resistivity on YBa_2 Cu_3 O_(7-δ) sample and try to explain the trend of YBCO thermoelectric value by existing theory.
