Alkali-metal Na Adsorption and Promoted Oxidation on Si(100)2×1 Surface

The alkali-metal Na adsorption on Si(100)2×1 surface and its promoted oxidation and Si oxidegrowth have been investigated by means of thermal desorption,work function,Auger electronspectroscopy and photoemission electron spectroscopy.The experimental data showed that therewas a new state,interface electron state,near the Fermi level after the deposition of Na atoms.It wasfound that the presence of Na always caused an increase of the oxygen initial uptake whereas thepromotion of Si oxide growth was observed only at the coverage of Na greater than 0.5 ML.A newmechanism of Na-promoted Si oxide growth is suggested in this paper.     

差分式连续时间电流型CMOS跨导—电容低通滤波器

应用信号流图法对电流系统传递函数直接模拟，提出了一种新颖的差分式连续时间电流模式ＣＭＯＳ跨导－电容低通滤波器的实现方案。由于采用了差分式结构和电流负反馈，整个电路方案具有差分式结构和电流型电路的优点；并且仅使用最少数量的ＯＴＡ和电容，与数字ＣＭＯＳ工艺兼容，适于全集成。面向实际电路完成了ＭＯＳ管级的计算机仿真，结果表明，所提出的电路方案正确有效

利用地震分形属性钻前预测安全钻井液密度范围

为了对钻井过程中的井壁失稳问题进行有效控制,根据地震和测井信息的分形性质以及它们之间的密切联系,提出了综合利用地震记录的分形属性预测测井曲线并进而在钻前预测安全钻井液密度范围的模型。首先从井旁地震记录中提取出能全面反映地震非线性特征的分形属性,运用能充分利用样本信息的CUSI神经网络,建立已钻井段地震分形属性与测井数据之间的非线性映射模型,通过该模型预测未钻地层的声波和密度测井曲线。在此基础上运用井壁稳定分析模型,计算地层的孔隙压力、坍塌压力和破裂压力,从而在钻前预测安全钻井液密度范围。该方法在西部某油田的应用表明,用地震记录的分形属性钻前预测安全钻井液密度范围的方法具有良好的预测效果。该方法预测精度较高,操作简单易行。

激光结晶a-Si:H SOI离子注入和快速退火

本文对激光结晶a-Si∶H SOI结构砷注入和快速退火行为作了研究.a-Si∶H激光结晶有Lp-LCR,OD,FCR-2,FCR-1四个结晶区.用剖面电镜观察了结晶区的结构.扩展电阻测量表明Lp-LCR区中有两种扩散机制,即杂质在晶粒体内扩散和沿缺陷扩散.OD区中有三种扩散形式,除有上述两种以外,还有沿缺陷的扩散.首次比较了沿晶界和缺陷的扩散速度.
