    • Disclosed is a method for fabricating a white LED which comprises, as a single active layer, an InGaN thin film which enables emission of white light. The InGaN thin film is constructed by taking advantage of the spinodal decomposition of the ternary compound and rapid thermal annealing. When growing the InGaN thin film on an n-type GaN formed on a sappier substrate under a growth condition, the thin film undergoes spinodal decomposition into two phases which show photoluminescence of a wavelength range from violet to blue and from green to blue, respectively, after which the surface of the thin film is thermally stabilized by rapid thermal annealing and the photoluminescence of the In-deficient phase is improved, so as to give intensive white photoluminescence to the InGaN single active layer. The LED which recruits such a single active InGaN thin film is superb in light emission efficiency and can be fabricated in a significantly reduced process steps.
    • 公开了一种制造白光LED的方法,其包括作为单个有源层的能够发射白光的InGaN薄膜。 通过利用三元化合物的旋节分解和快速热退火构成InGaN薄膜。 当在生长条件下在形成在增幅器衬底上的n型GaN上生长InGaN薄膜时,薄膜经历亚稳态分解成两相,分别显示从紫色到蓝色和从绿色到蓝色的波长范围的光致发光, 之后通过快速热退火热稳定薄膜表面,提高了In缺陷相的光致发光,从而为InGaN单一有源层提供强烈的白色光致发光。 招募这种单一活性InGaN薄膜的LED在发光效率方面是极好的,并且可以以显着降低的工艺步骤制造。
