摘要:	AgSbTe2是一種相當好的熱電材料，具有相當低的熱傳導係數以及接近於1的熱電優值(ZT值)。一些文獻中有提到此材料在約600 K左右會產生第二相。因此，在這篇論文中，我們希望能夠研究在不一樣比例摻雜的Ge、Se，使材料的熱電性質上的改變；爾後我們也希望藉由熱示差掃瞄卡量計(DSC(Differential Scanning Calorimeter))來驗證其他文獻中的結果：約600 K左右可以得到第二相。為了使樣品混和均勻，在製備樣品時，利用熔融及搖勻(Melting and Shaking)的方法，也就是將樣品熔融之後進行搖勻的動作，在樣品燒結成塊材之前，得到相對較均勻的樣品。我們一共使用了5種的比例合成Ag(Sb1-xGex)Te2、AgSb(Te2-xSex)，分別為：x = 0.01~0.05。在樣品燒結完成以後，將樣品進行破管，磨成細粉，為了在之後利用電漿火花燒結(SPS (Spark Plasma Sintering))壓製出我們所需要的樣品。進行量測時，我們利用了雷射熱擴散量測系統(LFA(Laser Flash Apparatus))以及賽貝克係數與電阻率量測系統ZEM-3得到我們所需要的熱傳導係數、電傳導係數、賽貝克係數(Seebeck係數)、以及功率因子(Power factor)，利用這幾個得到的參數計算，得到我們所需要的熱電優值(ZT值)。其後我們也為了知道是否在600 K左右得到相變，利用了熱示差掃瞄卡量計(DSC(Differential Scanning Calorimeter))來做量測，在600-630 K左右我們兩種摻雜的樣品得到了第二相的變化，使熱傳導係數大幅下降。最後我們得到最高的熱電優值為摻雜Ge比例0.03的樣品，在680 K左右可以得到熱電優值為2.5；Se摻雜比例0.05的樣品，在660 K可以達到2.02左右。
