Another approach in enhancing the light extraction efficiency of AlGaInP LED was accomplished using a surface roughening process. In this process, the Au(170 nm)/AuBe(260 nm)/Au(170 nm) ohmic contact layers were first deposited on the GaP window layer. After the alloy annealing process (480°C for 10 min), the Be atoms will diffuse into the GaP top layer and form non-uniform clusters. The LED samples were then immersed into a mixture 3H3PO4:1H2O2:1H2O solution for 6 min, resulting in a rough GaP surface. The luminous intensity of the AlGaInP LED can increase from 42 to 50 mcd, that is, an 18% enhancement can be achieved via the present non-photolithography surface roughening process.Keywords: LED, AlGaInP, Cu substrate, Reflector, Surface roughening
在实验的第二部份是开发磷化镓窗口层之粗化制程,我们是藉由正面金/铍欧姆接触电极之熔合制程,使铍扩散至磷化镓层,同时利用铍渗入磷化镓造成之特殊组成,可形成不均匀之蚀刻阻挡,而在磷化镓表面形成粗化,我们发现480℃、10分钟的熔合制程,加上浸泡磷化镓蚀刻溶液6分钟,可将四元发光二极体之发光亮度由42 mcd 提升到50 mcd,经由此无光罩粗化制程可将亮度提升18%,明显提升磷化铝铟镓发光二极体之外部量子效率。

The results showed that plant height increasing speed was significantly slow at the former and middle stage when K level was above 180 kg/hm2.On the contrary,the height of case-hardened plant improved markedly.When the K level was above 135 kg/hm2,the stem girth and maximal leaf area differed significantly as compared with CK,so did LAI.Yield and product value per unit area took the first place when 180 kg/hm2 potassium was used.Average price and proportion of middle and first grade tobacco leaf of 225 kg/hm2 potassium treatment were the highest as compared with other treatments and CK.Four economic characters of the two treatments differed at obvious significant level as companied with CK.The total sugar and K2O were increased,nicotine, total N,protein and Cl- were decreased with increased K levels.The potassium lacked symptom was alleviated with increased K levels,no symptoms was observed when 180 kg/hm2 potassium was used,the degree of weather infected fleck was decreased when the K levels was increased.
结果表明,在烟株生长前中期,当施钾量达到180 kg/hm2以上时,株高增长显著变慢,而定型株高则显著增高;茎围和最大叶的面积在施用135 kg/hm2以上的处理与CK之间的差异性达到极显著水平,叶面积指数也存在显著差异;单位面积产量和产值以施用180 kg/hm2的处理居首位,中上等烟比例和均价以施用225kg/hm2的处理最高,这两种处理的以上4个经济性状与CK之间存在极显著性差异;烟叶中的总糖和K2O含量随施钾量的增加而上升,烟碱、总氮、蛋白质和C-含量则下降;缺钾症状随施钾量增加而减轻,至施用180kg/hm2时已无缺钾症状;烟叶气候斑的发生程度也随施钾水平的提高而减轻。

Results: In contrast to negative expression in normal oral mucosa, survivin was expressed in 42 of 50 (84%) cases of oral squamous cell carcinoma samples. There was no significant correlation between survivin expression and age and sex. In squamous cell carcinoma tissues, the expression of Survivin gene stepped up following malignant degree, but the positive rate of Survivin was not statistically significant.
