    Abstract: 近十幾年來因全球暖化所以再生能源倍受重視,除了熟知的風力發電、太陽能發電與水力發電外,熱電發電也成為一個越來越廣為人知的綠色能源。
    熱電材料能將熱能直接轉換為電能,根據此特性熱電材料能應用在許多產生廢熱的裝置上,且轉換過程並不會再對環境造成額外汙染,是一個非常有發展潛力的綠色能源。而熱電材料的好壞可以由ZT優值判斷,越好的熱電材料具有越高的ZT值,因此盡可能地提高ZT值也是我們不斷追求的。
    本研究嘗試各種不同組合的鎂矽錫比例,並個別測試不同的溫度和時間使粉末充分反應,過程中評估數據並多方嘗試改善,我們會選擇適合的元素摻雜其中來提高熱電性質。
    透過實驗我們可以得出此燒結方式的最佳製程參數,將粉末經過冷壓以及退火後可以得到良好的試片,再與實驗室其他同學相匹配的熱電材料來建構熱電模組,最後量測此模組的熱電特性,在最大溫差到達136℃時,功率為3.306μW。
    ;In recent decades, thermal power generation has become an important topic.Thermoelectric materials with high ZT values is on the demand for this purpose.
    In this study, p-type Mg2(Si,Sn) by different process temperatures and parameters was tested to improve the thermoelectric properties. A module was fabricated by the best process control and the maximum power output is 3.306μW under 136℃ temperature difference.
