Abstract:	環境變遷與能源議題是現今社會上很大的問題，熱電材料是一個以材料本身，使得熱能與電能之間能夠互相轉換，並在轉換過程中無任何廢物及汙染產生的發電方式，若能有效利用將是十分環保的能源使用方式，將其應用於廢熱回收、溫差發電、熱電置冷等，當中影響熱電效應的好壞主要取於熱電材料本身具有的熱電優值(ZT)。本研究以探討熱電材料的特性及將其做成模組探討ZT值，從材料製作到模組皆由本實驗室完成，將粉末冷壓成塊材，利用不同溫度退火，製作出結構及特徵峰值明確的粉末，再次冷壓退火，製作出結構穩固的試片，利用這個試片做成模組，並量測其特性。 ;Climate change and energy issues are big topics in today′s society. Thermoelectric power generation is one kind of power generation methods that uses materials themselves to convert heat into electricity without any waste or pollution during the conversion process. The effect can be applied to waste heat recovery, temperature difference power generation, thermoelectric cooling, etc. The impact of the thermoelectric effect is mainly taken from the thermoelectric quality (ZT) of the thermoelectric material. This study explores the characteristics of thermoelectric materials and modules to investigate the ZT values. From materials to module fabrication, we innovate a new method to produce Mg2(Si,Sn) nanopowders and bulks by powder mixing, cold-pressing and different annealing processes, and a module for thermoelectric characteristic measurement.
