  • 隨著國內半導體與光電產業的蓬勃發展,相關製程技術不斷提昇,微型化之電子或機械元件的熱傳問題分析,已從巨觀邁入微觀現象的層面,本文以微奈米尺度介電材質的一維薄膜微觀熱傳現象作為研究方向,以聲子輻射熱傳方程式作為理論基礎,並假設傳熱情況為雙熱通量模型,使用數值分析的有限差分法進行模擬,探討鬆弛時間、薄膜性質與薄膜材質對薄膜內部溫度及熱通量分布的影響。


    Manufacturing technologies develop with internal semiconductor and photoelectric industry. The problem about heat transfer of microelectronics or micromachines have entered from macroscale to microscale. This study discusses micro/nano scale heat transfer phenomenon of one-dimension film in dielectric materials. Assume the condition of heat transfer is two-flux model, according to equation of phonon radiative transfer, using finite difference method to numerical analysis. Observes the distribution of temperature and heat flux in film when relax time、film properties and film materials change.
