Abstract:	在近年來，全球都在追求綠能發電，綠能能遏制地球環境的劣化，所以現今積極地開發綠色能源為主要的研究議題，而熱電能本身是種非常良好的綠色能源，熱電效應是指一種熱能與電能互相轉換的效應，其環保價值非常高，可以應用於，例如廢熱回收、溫差發電、熱電致冷等等…。而影響熱電效應好壞取決於材料本身的熱電優值(ZT)。因此提升材料ZT為其中最為重要的研究。本研究主要透過在摻雜反應製作出P、N-type 奈米粉末，在與鎂錫粉末混合並冷壓成錠，接著在不同溫度下做退火反應，並得到何種溫度下最好的熱電特性，再使用此錠，來製作其模組，並量測其特性。;In these years, the power consumption has been reaching new records, consuming lots of energy from coal, gasoline, fuel, and nuclear. These energy resource has their own drawbacks, resulting in pollutions and hazardous substance. Due to the concern of environmental sustainability, clean energy is in demand and in dire need. In this study, P and N-type nanopowders were prepared by mechanical grinding, followed by doping and mixing to obtain the designed composition. Then it was cold-pressed into ingots and annealed at different temperatures to study the thermoelectric properties. The thermoelectric module was made and measured to test its conversion efficiency.
