能源是全球議題最重要議題之一，為了保護地球及永續環境，再生能源的開發已是迫在眉睫。現今已經有很多研究在尋求更好的熱電轉換材料。熱電效應是熱能與電能的轉換，熱電材料為熱能轉換成電能的材料，透過熱電材料的熱電轉換效率，將廢熱轉換成電能，可以使更多的應用續航力提升，也可以改善溫室氣體排放的問題。故熱電轉換元件成為近代綠色能源的新希望。 本研究著重於二維及三維塊材的Seebeck係數量測，分別以矽鍺二維量子井多層薄膜及氧化鋅塊材為實驗對象。薄膜基板可直接由探針量測，粉末在製作成塊材後，需製作電極後方可在室溫環境至700 K之間進行量測。本研究成功探討矽/鍺基材料及氧化鋅的Seebeck係數，以作為往後熱電學理之研究基礎。 ;Renewable energy has been one of the important global issues due to the protection of the environment and sustainability. For this purpose, there have been many studies in the search for good thermoelectric materials. Thermoelectricity is the conversion between heat and electricity. By converting waste heat into electricity through the thermoelectric materials, the circumstances of greenhouse and gas emissions can be mitigated. Therefore, thermoelectric conversion element would become the new hope of modern green energy. In this study, the apparatus for Seebeck coefficient measurement was demonstrated for 2-dimensional thin film and 3-dimensional bulk materials. The Si/Ge based multiple quantum well was measured directly by the probes from room temperature to 400 K while the bulk was measured up to 700 K with the help of patterned electrodes. This study demonstrated the method for Seebeck coefficient measurement, as well as the basis for thermoelectric understanding.
