Abstract: Ⅲ-nitride在最近已被廣泛的研究與應用在藍光的發光元件,但是目前多數人所著重的是在三元的InGaN與AlGaN,另一三元化合物AlInN卻較少受到注意。其實AlInN的發光波長範圍也就是其能帶間隙能夠有很大的調變性,晶格同樣也具有較廣範圍,所以也能與元件有較好的晶格匹配。因此我們採用理論的模擬軟體來計算一些原始的材料特性,將材料由最原始的原子排列組成,進而算出AlxIn1-xN相對的band-gap energy 及bowing parameter (b)值。我們的模擬結果顯示:理論上wurtzite晶格的本質性 AlxIn1-xN (0≦x≦1)材料有很明顯的bowing現象,其bowing parameter值為:b = 3.326 (eV)。
