1·Gallium nitride is a semiconductor used to create bright-blue LEDs.

氮化镓是一种用来生产亮蓝色LED的半导体。

2·Most of the white LEDs now on the market are based on gallium nitride.

目前市面上多数的白色发光二极管都是基于氮化镓的.

3·The researchers used a gallium nitride semiconductor in the proof of concept tests.

研究者们在“概念验证”实验中使用的半导体材料是氮化镓。

4·A gallium nitride LED on sapphire has a typical internal quantum efficiency of around 70%.

基于蓝宝石的氮化镓发光二极管的一般内量子效率约为70%。

5·Yet even at this early stage he thinks gallium nitride-on silicon LEDs would make commercial sense.

即使是在目前的早期阶段，他认为硅基的氮化镓发光二极管就已经具有商业意义了。

6·In the early 1970s RCA did succeed in coaxing some light from gallium nitride-based diodes, but its blue LEDs were inefficient and dim.

20世纪70年代早期RCA的确成功的从氮化镓二极管中析出些许光线，但是它的蓝色LED太暗并且功效低下。

7·He found that producing p-type gallium nitride, which made use of ammonia at high temperatures, trapped hydrogen atoms inside the crystal.

他发现在生成p型氮化镓的时候需要利用高温氨，以致于把氢原子引入了晶体之中。

8·Gallium nitride turned out to be difficult to grow without defects, and although n-type gallium nitride could be made easily, p-type could not.

氮化镓最终被发现很难做到没有瑕疵，即使n型氮化镓很容易被造出，p型却不然。

9·Gallium nitride is grown by plasma-assisted molecular-beam epitaxy on (111) and (001) silicon substrates using hafnium nitride buffer layers.

氮化镓是增长了等离子体辅助(111)和分子束外延(001)硅衬底上氮化硅缓冲层使用铪。

10·At present these LEDs are made in machines similar to those used to make silicon chips, by depositing layers of gallium nitride on sapphire-based wafers.

目前LED同硅晶片的制作设备类似，都是通过在蓝宝石衬底片上沉淀氮化镓层实现。
