In order to deposit good films, we need to study the uniformity of plasma density and the plasma density under different gas pressures and powers. The plasma density was diagnosed by a Langmuir probe. The optical emission spectroscopy (OES) of CH4 and H2 discharge was obtained with raster spectroscopy, with characteristic peaks of H and CH achieved. Diamond-like carbon films were achieved based on the study of plasma density and OES and characterized by atomic force microscope (AFM), X-ray diffraction instrument (XRD), Raman spectroscope and profiler. 相似文献

An investigation was made into the nitrogen-trimethylgallium mixed electron cyclotron resonance (ECR) plasma by optical emission spectroscopy (OES). The ECR plasma enhanced metalorganic chemical vapour deposition technology was adopted to grow GaN film on an α-Al2O3 substrate. X-ray diffraction (XRD) analyses showed that the peak of GaN (0002) was at 20 = 34.48°, being sharper and more intense with the increase in the Ne: trimethylgallium(TMG) flow ratio. The results demonstrate that the electron cyclotron resonance-plasma enchanced met- alorganic chemical vapor deposition (ECR-MOPECVD) technology is evidently advantageous for the deposition of GaN film at a low growth temperature. 相似文献

1.利用纵横信息技术增加学生的知识积累
鲁迅说过:“必须如蜜蜂一样,采过许多花,这才能酿出蜜来。”学生必须观察、阅读、大量的积累,写作时才会有话可说,有材可选,下笔才会有神,表达才会有个性、有特色。那么,怎样在训练学生录入汉字的过程中让学生增加知识积累,起到事半功倍的效果呢?我们主要从三个方面引导学生:①利用纵横信息软件中的词语游戏软件,教师精心选择练习的词语,让学生在练习四字词时增加四字词语和成语积累。 相似文献
