有机电致发光器件的新型薄膜封装技术研究

针对有机电致发光器件(OLED)在空气中水汽和O2作用下寿命下降的问题,提出一种对OLED进行薄膜封装方法。封装薄膜由电子束蒸镀Al2O3薄膜和原子层沉积(ALD,atomic layer deposition)Al2O3薄膜相结合形成。利用Ca薄膜电学测试方法测定封装薄膜的水汽透过率(WVTR)。具体实现方法是,采用玻璃作为衬底,在100nm的Al电极上蒸镀200nm的Ca膜,然后对整个系统进行薄膜封装,只留出Al电极的一部分作为探针接触电极。实验发现,采用电子束蒸镀结合ALD的Al2O3薄膜封装,Ca薄膜变成透明的时间比未封装或采用单一结构封装得到了延长。为了检验薄膜封装效果,制作了一组绿光OLED,器件结构为ITO/MoOX(5nm)/mMTDATA(20nm)/NPB(30nm)/Alq3(50nm)/LiF(1nm)/Al,实验结果表明,本文提出的薄膜封装方法对器件进行封装,器件的寿命得到了延长。

准垂直肖特基二极管电极间距对耐压的影响

研究了不同电极间距对准垂直肖特基势垒二极管（SBD）正反向I-V特性，尤其是击穿电压和漏电的影响。通过制备不同电极间距的准垂直GaN SBD，测量不同电极间距器件的击穿电压和反向漏电变化。测量发现当电极间距小于器件台面刻蚀深度时，器件的击穿电压随着电极间距的增大而增大；当电极间距大于台面刻蚀深度时，器件的击穿电压随着电极间距的增大而几乎不发生变化。利用Silvaco软件进行了一系列的仿真研究，发现SBD的峰值电场强度不仅取决于电极间距，同时还受限于台面高度。研究表明在准垂直SBD研制中，为得到高击穿电压，电极间距应匹配器件台面的高度。     

透明叠层结构Ag/MoO_3/Ag阳极对绿光OLED器件性能的影响

本文采用一种结构为Ag/MoO_3/Ag的金属/氧化物/金属(M_1/O/M_2)叠层替代ITO作为OLED器件的阳极,研究Ag/MoO_3/Ag叠层结构变化对于OLED器件电极透过率、亮度、光谱等性能的影响。实验采用真空蒸镀方法制备了一系列器件,器件结构为Ag/MoO_3/Ag/MoO_3(10nm)/NPB(40nm)/Alq_3(60nm)/LiF(1nm)/Al(150nm)。对比器件的电压-电流密度、电压-亮度、光谱特性等数据,表明Ag/MoO_3/Ag的结构为20/20/10(nm)时,器件性能较好。在驱动电压为11V时,其亮度达到18 421cd/m~2,电流效率为2.45cd/A;且因器件中存在微腔效应,其EL光谱蓝移,半高宽变窄。但考虑到530nm处其电极透过率仅为17%,所以经换算该器件实际发光亮度比ITO电极器件更高。该Ag/MoO_3/Ag叠层阳极制作相对简单,经优化后在顶发射和柔性OLED器件方面将具有一定的应用前景。

The CDMA Mobile System Architecture

The architecture of the CDMA mobile system (CMS) is developed based on three function groups - service resource, service control, and service management groups. In this paper, the CMS architecture is discussed from the point of view of implementing these functions. The variable length packets are used for transmission. The synchronization clock signals are derived from the GPS receiver. The open loop and closed loop techniques are used for the power control. The internationally accepted signaling and network protocols are employed. The call control for the primary services is designed to provide efficient mobile telecommunication services. The softer handoff is implemented in one card. The mobile assisted handoff and the network assisted handoff are employed in the soft and hard handoffs. The authentication is based on the secret data which includes random numbers. The management functions, which include the location management, resource management, cell boundary management and OAM management, are implemented to warrant the system efficiency, maximum capacity and high reliability. The architecture ensures that the CMS is flexible and expandable to provide subscribers with economic and efficient system configuration. The dynamic power control, adaptive channel allocation, and dynamic cell boundary management are recommended for future work.     

La réglementation de la cryptologie en france de 1990 à 2005

The cryptology has been for a long time the fact of the army. The cryptography was considered not as a mean of communication but as a weapon. Nowadays, in France the cryptography can be used with a free access. The supply, the importation and the exportation of means and services of cryptology have been liberalized. The purpose of this article is to study the relations between liberty and security in the frame of the cryptology, for France. The process of liberalization can be explain by the deregulation in the telecommunication field for a small part, and by the emergence of the electronic trade for the biggest part. The security has not been forgotten. The cryptology is not a tool as the others. Some few restrictions of authorizations and declarations have been maintained. The non respect of these restrictions can generate sanctions not always used. The relation liberty/security appeared also in the electronic signature, adopted by the European Union in 1999 and in the European countries, especially in France. The electronic signature, by the way of the certification services need to use the cryptology, to be recognized and protected. The industrials have succeed, with the liberalization of the cryptology and their software, to build a famous system, not already finished: the security of the society information.

The intestinal gland of Trichinella spiralis with emphasis on morphology and antigenicity

The intestinal gland of muscle larvae and adult worms of Trichinella spiralis was investigated with emphasis on its morphology and antigenicity. The gland is situated at the junction between the stichosome and the ampullar portion of the midgut. The cytoplasm was characterized by the presence of cytoplasmic granules. The granules, measuring 1 micron at maximum, were round or sometimes irregular in shape, and of homogeneous appearance with medium to high electron density. Rough endoplasmic reticulum was not prominent. Glycogen granules were absent. The gland was surrounded externally by the basal lamina and hemolymph. The cell membrane was extensively invaginated, and coated pits and vesicles were often observed. The cytoplasm was rather eosinophilic, PAS-negative, and stained red or yellow by AZAN. The cytoplasmic granules were antigenic against trichinosis sera from humans and rats, and cross-reacted with sera from paragonimiasis, trichuriasis and gnathostomiasis patients.
