在本篇論文研究中，我們討論許多電子元件、光學設備因為功率不斷的提升造成結構內部產生熱效應的問題，這些熱的累積會造成元件的使用壽命縮短、發光效率降低等負面影響，因此散熱變成很重要的課題。在傳統的散熱裝置上，大多是利用金屬材料的熱傳導、熱對流特性來達到降溫的效果，而我們提出利用〝膜堆〞熱輻射的特性，來達到效果更好，體積更小的散熱裝置。
我們利用三層厚度為奈米等級的介電質、金屬堆疊成膜堆，並設計結構讓膜堆在紅外波段有很好的吸收特性，並比較在相同大小下，膜堆的降溫效果與其他常見的熱傳導金屬效果的差異，也比較不同吸收波段的膜堆是否會造成散熱效果的差異。論文中也討論當輸入功率提升時，各種不同的結構溫度的比較，最後並透過有限元素分析軟體COMSOL驗證我們理論及方法的正確性。

This work develops and analyzes a compact layered film for light emitting diode (LED) heat dissipation based on the method of passive cooling. That is externally applied input energy is ignored here. A feature of high absorptance of our propose film at atmospheric transmission region can be observed. The corresponding admittance diagram and absorptance spectra are also calculated and investigated. Electromagnetic and heat diffusion simulations based on the finite element method (FEM) are accomplished to verify that the design of the proposed film possesses the ability of decreasing temperature of LED with various heat input. Considering the typical LED in work (1 mm2 surface area with heat generation of 1 watt), the temperature can be decreased. A decrease of temperature can be achieved as compares to the LED without adopting our proposed design. This proposed design has potential application in the field of thermal emitter, photovoltaic-based device, and high power devices.
