不同衬底生长ZnO薄膜的结构与发光特性研究

采用射频磁控溅射方法分别在蓝宝石(Al2O3)(0001)和硅(100)衬底上制备ZnO薄膜．通过X-光衍射测量与分析表明两者都沿C轴方向生长，在Al2O3衬底上的ZnO薄膜结晶质量优于在Si衬底上的薄膜样品．然而，由原子力显微镜观测发现在Al2O3衬底上的薄膜晶粒呈不规则形状，且有孔洞，致密性较差；而在Si衬底上的ZnO薄膜表面呈较规则的三维晶柱，致密性好．光致发光测量表明，不同衬底上生长的ZnO薄膜表现出明显不同的发光行为．

A Study on the Surface Structures of Viscose-based Activated Carbon Fiber by FT-IR Spectroscopy and XPS

Using viscose fiber (VF) as starting material and common steam as activating agent, formation of oxygen structures in activated carbon fiber is investigated. In the preparation of samples, VF was first heated at temperatures between 450℃ and 900℃ in N_2 artmosphere. Then, in a successive activation stage, the product carbonized at 600℃ was activated in steam at 450-900℃ for 30 min, and at 600℃ for 5-30 min. The other carbonization products were activated at 600 and 900℃ for 30 min respectively. The products activated at 900℃ were then activated at 450℃ for 30 min again. The starting materiah carbonized products and all activation products were examined by FT-IR spectroscopy and some products were examined by X-ray photoelectron spectroscope (XPS). And the yields of the carbonized and activated products were calculated. By analysing these spectra, the amount of oxygen-containing functional groups of the activated products attained under various activation time, various activation temperature and     

Switched Capacitor Network Analysis by Means of TCM

The totally coded method (TCM) reveals the same objective law, which governs the gain calculating for signal flow graph as Mason formula does. This algorithm is carried out merely in the domain of code operation. Based on pure code algorithm, it is more efficient because figure searching is no longer necessary. The code-series (CS), which are organized from node association table, have the holoinformation nature, so that both the content and the sign of each gain-term can be determined via the coded method. The principle of this method is obvious and it is suited for computer programming. The capability of the computeraided analysis for Switched Capacitor (SCN) can be enhanced.
