| dc.description.abstract | 近年來全球暖化嚴重性急遽上升，地球環境及生態也因此不斷地改變，因此開發綠色能源逐漸被世人所重視，並積極地開發相關研究議題。我們知道綠能發電能減緩甚至改善地球生態劣化的程度，而其中熱電效應之應用為一種優秀的方式。熱電效應，一種熱能和電能能夠相互轉換的效應，其在環保上的價值非常高，可應用於廢熱回收、溫差發電、熱電致冷等。當中影響熱電效應的好壞主要取決於熱電材料本身具有的熱電優值(ZT)，因此，致力提升ZT優值在熱電材料研究中最為重要。
本研究透過矽摻雜反應，製作出N/P type之奈米粉末，與鎂錫粉末加以混合後冷壓成塊材，再用不同溫度的環境做退火反應，評估出熱電特性最好的製程，最後使用其製程製備塊材來製作模組，並量測其熱電上之特性。 | zh_TW |
| dc.description.abstract | 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. | en_US |
