On the two methods of kinetic theory of ECRM

The kinetic theory based on the expansion of local field in the guiding center coordinate system, presented by paper[1]–[3], has successfully developed into a theoretical system. The mathematical background and physical explanation of setting up the guiding center coordinate system is expounded in the paper. By using the methods of the guiding center and waveguide coordinate systems respectively, the same dispersion equations for interaction of an axially symmetrical single momentum electron beam with TE_mn field in the circular waveguide are rigorously derived. A number of mistakes in paper[4] are indicated as well.     

硅薄膜沉积过程中等离子发光基团的一维空间分布研究

使用光发射谱(OES)对甚高频等离子增强化学气相沉积(VHF-PECVD)技术沉积硅薄膜时的等离子体发光基团的空间分布进行了在线监测和研究. 研究表明：等离子体的不同发光基团都存在着一个中间强度较大的区域和两边电极附近的暗区;增大硅烷浓度和提高辉光功率都会增大SiH^*峰强度;硼烷的加入,使得SiH^*和Hα^*峰强度增大,但硼烷流量变化的影响很小;硼烷流量增大,材料的晶化率下降,而I_{［Hα^*］关键词： 甚高频等离子增强化学气相沉积 等离子体 发光基团 空间分布}     

Excited states in126Ba

The K=3/2 ₁ ^T rotational band has been identified in⁹⁹Y with a band-head energy of 536 keV. This result is in contradiction with previously reported data, but is in agreement with predictions of the IBFM/PTQM model.

The covariant-derivative regularization program is discussed ford-dimensional gauge theory coupled to fermions in an arbitrary representation.     

气相外延GaN的拉曼散射

测量了在蓝宝石衬底上气相外延生长GaN的拉曼散射谱.除观察到已被确认的两个E2,一个A1(TO)和一个E1(TO)声于振动以外,在734±3cm-1处观察到一个散射峰且从实验上确认其为GaN的纵向光学声子模E1(LO).而且发现其强度与外延层晶体质量密切相关.A1(TO)和高频E2散射峰相对强度变化显示不同生长条件引起的外延层质量的变化.

声表面波MIM隧道发光二极管

我们在研究MIM隧道发光结(金属-绝缘层-金属)的过程中,首次以表面声波代替表面随机粗糙度的作用,将MIM结制作在声表面波场中,结果使结的发光效率、发光强度、稳定性、均匀性都有改善.本文介绍了结的基本结构,基本工艺,阐明了结的发光机理,讨论了结的Ⅰ-Ⅴ特性曲线和光谱曲线,根据结具有显著的负阻现象,我们设计出了一种新型的开关器件.
