Abstract
Description
ここで、Sは、1度当たりのマイクロボルト(μV/K)で表したゼーベック係数である。
Z=S2σ/κ
ここで、σおよびκは、それぞれ導電率および熱伝導度である。逆数Kで表した良さの指数Zの熱電数字は、熱電発電装置で使用することができる熱電材料の熱的および電気的特性である。熱電発電装置の効率を改善するための重要事項の1つは、電気抵抗が低く、ゼーベック係数が高く、熱伝導度が低い優れた効果の熱電膜を開発することである。
p型熱電脚部32、34の対向端部にそれぞれ接続している第1の電気リード線24および第2の電気リード線30を備えることができる。
る。
しかし、過剰分は、約10原子百分率Te過剰分から約30原子百分率Te過剰分の範囲であればよい。半導体化合物の他の実施形態の場合、熱電発電装置10は、複数のn型およびp型熱電脚部32、34を含むことができる。p型の各熱電脚部34は、上式(Bi0.15Sb0.85)2Te3+約10原子百分率Te過剰分から約30原子百分率Te過剰分を有する半導体化合物からできている。
