基片温度和退火对DdIn2O4薄膜光学性质和载流子浓度的影响

对射频反应性溅射Cd-In合金靶制备的透明导电CdIn2O4薄膜，研究了基片温度及沉积后在氩气流中退火对薄膜的透射、反射和吸收光谱，光学常数和载流子浓度的影响。结果表明：提高基片温度减少了薄膜的载流子浓度，退火增加了薄膜的载流子浓度。随着基片温度提高，薄膜折射率n和消光系数κ的短波峰将逐渐蓝移，而退火使其出现红移。基片温度和退火对薄膜光学常数的影响与其对薄膜载流子浓度的影响是一致的。在制备CdIn2O4这样一种对于沉积方法和沉积条件极为敏感的透明导电薄膜的沉积过程中，这一现象对于实时监控具有极为重要的意义。

带用横向射流的三维超声速湍流流场分析

应用显式的五阶WENO格式，结合k-ω湍流模型，求解三维Favre平均N－S方程，计算了从方孔横向喷出的声速气流与马赫数为3．0的超声速气流的干扰流场。结果表明，在射流上游，射流的阻碍便超声速气流产生分离，形成两个主要的回流区域，主回流导致在方孔射流两侧形成马蹄涡区域，射流下游存在低压区域，形成较小的回流以及一对螺流形旋涡。

What Is Its Real Existing Form?——Theoretical and Experimental Studies on 2-Mercaptobenzothiazole

1 INTRODUCTION The study of heterocyclic molecules with aroma- tic rings and their absorptions on metals is of con- siderable importance from both theoretical and te- chnological points of view. These molecules are in- teresting because of their applications as corrosion inhibitors and flotation collectors, and their abilities to form self-assembly layers[1]. 2-Mercaptobenzo- thiazole (C7H5NS2, in the following MBT) is an important heterocyclic molecule, which can be used as corrosion …

Recombination Efficiency in Double-Layer Organic Light-Emitting Devices

We analyse the influence of properties of organic/organic interface (OOI) on the characteristics of recombination efficiency of organic double-layer light-emitting diodes. Based on the disordered hopping theory model, spatial and energetic disorder of hopping states are also discussed for the case of space charge limited currents in hole transmitting layers but injection-limited currents in electron transporting layers. The results show that the recombination efficiency increases firstly and then decreases for different OOI parameters, and there is a maximum value changed with different spatial disorder parameters and energetic disorder scale. Different spatial disorder parameters make carrier mobilities change greatly, and the energetic disorder scale causes various localized state densities. Our calculated results are qualitatively in agreement with the experimental data.
