全球暖化的問題已受到全世界的重視，找尋一個環保且友善環境的再生能源非常重要。隨著奈米科技的進步，熱電材料是其中一個優秀的選擇，它能在熱能與電能之間做轉換，利用溫差來產生電能進而提高能源的使用率，適合運用在工廠或是汽車這類有大量廢熱的地方。 熱電材料的特性隨著材料的不同而改變，其中氧化物半導體具有良好的熱穩定性、化學穩定性、無毒且環保，是一種良好的熱電材料。 本論文研究氧化鋅材料，經由對氧化鋅做不同的掺雜製作出N-type試片與P-type試片，N-type材料是對氧化鋅掺雜2at%的Al2O3及CeO2，而P-type材料是對氧化鋅掺雜0.192at%的ZnP。並利用銀膠與鎳膠、銅金屬片、鎳金屬片、鉭金屬片當作接觸金屬製作出熱電模組，並在不同溫度下量測其輸出功率。 ;The issue of global warming has garnered worldwide attention, highlighting the importance of seeking environmentally friendly and sustainable energy sources. With advancements in nanotechnology, thermoelectric materials have emerged as an excellent option for converting heat into electricity. By harnessing temperature differentials, these materials can generate electrical power, thereby enhancing energy efficiency. Consequently, they find practical applications in settings such as factories or vehicles that generate substantial amounts of waste heat. The characteristics of thermoelectric materials vary based on the specific materials employed. Among them, oxide semiconductors possess desirable attributes such as thermal stability, chemical stability, non-toxicity, and environmental friendliness, making them an ideal choice for thermoelectric applications. This study focuses on zinc oxide (ZnO) materials. N-type and P-type samples were prepared by doping ZnO with different elements. The N-type material was doped with 2 at% Al2O3 and CeO2, while the P-type material was doped with 0.192 at% of ZnP. To construct thermoelectric modules, contact metals such as silver paste, nickel paste, copper foil, nickel foil, and tantalum foil were employed. The output power of these modules was measured at various temperatures.
