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。     

Studies on the Adsorption of Asymmetrical Triblock Copolymers by Scheutjens-Fleer Theory and Monte Carlo Simulation

The adsorption of asymmetrical triblock copolymers from a non-selective solvent on solid surface has been studied by using Scheutjens-Fleer mean-field theory and Monte Carlo simulation method on lattice model. The main aim of this paper is to provide detailed computer simulation data, taking A8-kB20Ak as a key example, to study the influence of the structure of copolymer on adsorption behavior and make a comparison between MC and SF results. The simulated results show that the size distribution of various configurations and density-profile are dependent on molecular structure and adsorption energy. The molecular structure will lead to diversity of adsorption behavior. This discrepancy between different structures would be enlarged for the surface coverage and adsorption amount with increasing of the adsorption energy. The surface coverage and the adsorption amount as well as the bound fraction will become larger as symmetry of the molecular structure becomes gradually worse. The adsorption layer becomes thicker with increasing of symmetry of the molecule when adsorption energy is smaller but it becomes thinner when adsorption energy is higher. It is shown that SF theory can reproduce the adsorption behavior of asymmetrical triblock copolymers. However, systematic discrepancy between the theory and simulation still exists.The approximations inherited in the mean-filed theory such as random mixing and the allowance of direct back folding may be responsible for those deviations.
