摘要(中)

本論文理論討論量子點分子製作的冷卻器。隨著奈米元件的普及，奈米積體電路的散熱問題就顯得愈發重要，奈米積體電路的散熱問題愈來愈受重視並開發奈米冷卻器來解決，因此。我們利用Anderson模型來描述冷卻器。其主要結構為金屬電極及半導體的量子點分子。冷卻器的電流與電子熱流我們運用格林函數來推導出解析的形式。本理論也引進適當的聲子熱流模型，來討論聲子熱流在冷卻器的降溫特性中所扮演的角色。

摘要(英)

We have theoretically investigated the properties of solid state cooler made of semiconductor quantum dot molecules. It is important to solve heat problems of circuits with nanoscale electronic components. Therefore, the design of nanoscale-coolers is desirable. We use the Anderson model to describe the Hamiltonian of solid state cooler made of quantum dot molecules. The electron and heat current of cooler are derived by the Green’s function technique. We also used an empirical model to include the phonon heat current. The temperature difference of cooler arising from phonon thermal conductance is discussed and analyzed.
