Description
本出願は、2006年6月26日付けで出願された米国仮特許出願第60/805,805号「Increasing the Seebeck Coefficient of Semiconductors by HP/HT Sintering」(HP/HT焼結による半導体のゼーベック係数の向上)に対して優先権を主張するものであり、参照により当該米国仮特許出願の開示内容の全体を本明細書に組み込むものとする。
(連邦政府の資金援助を受けた研究開発に関する記載)
該当せず。
(共同研究契約書)
該当せず。
(ディスク上の資料の参照による本明細書への組み込み)
該当せず。
例えば、テルル化ビスマス(Bi2Te3)およびテルル化鉛(PbTe)は、200μV/Kを超える最適化されたゼーベック係数を有するものとして一般に使用される半導体熱電材料の2つである。
材料のゼーベック係数最適化には、一般に、出発物質の化学量論的作用をドーパント材料でわずかに修正した合成方法が伴う。多くの場合、これにより完全に組成の異なる材料が生まれる。また、特定の材料組成のゼーベック係数を予測する容易な方法もない。
そのため、ゼーベック係数の絶対値が大きい材料が依然として必要とされている。さらに、必ずしも材料へのドーパント追加を必要とせずに材料のゼーベック係数を向上させる方法も依然として必要とされている。本明細書の実施形態は、以上に述べた必要性等に応えるものである。
