聚氨酯-聚丙烯酸酯共聚乳液的成膜和性能

通过XPS和接触角测试研究了聚氨酯-聚丙烯酸酯共聚乳液在不同基材上的成膜情况，并对共聚胶膜的耐水性和附着力进行了考察．由于该共聚乳液同时存在着亲水组分和疏水组分，所以它在不同的基材上成膜可导致其膜表面的组成成分不同，因而导致其耐水性和附着力也随基材而异。结果表明，亲水性的聚氨酯组分均富集于胶膜内部，但胶膜底层聚氨酯组分的含量却随基材的不同而不同。在憎水且表面张力较高的基材上，共聚胶膜的耐水性良好；共聚胶膜的附着力在表面张力较高的基材上也良好。     

钌基厚膜电阻传导模型初探

介绍钌基厚膜电阻的三种传导模型。三种模型都可以得到较满意的R—V曲线，不足处是链模型得出电阻率和导电相粒子形状及尺寸的关系和实验事实不符；有效介质模型不能反映厚膜电阻形成过程中众多因素的影响；渗透模型很多参数的获得有赖经验公式。渗透模型能反映烧结过程中更多因素的影响，并可解释方阻与导电相粒度及峰值温度的变化关系。

Kinetics of DyNi2 film growth by electrochemical implantation

Electrochemical implantation was performed at Ni electrodes to form DyNi₂ films at 0.55 V (vs. Li⁺/Li), 0.62 V, and 0.70 V for 0.5-5.0 h in a molten LiCl-KCl-DyCl₃ (0.50 mol%) system at 700 K. It was found that the DyNi₂ films grew linearly with time with coulomb efficiency of about 100%. The obtained growth rates were higher at more negative potentials, i.e., 0.47 μm min⁻¹ at 0.55 V, 0.32 μm min⁻¹ at 0.62 V, and 0.14 μm min⁻¹ at 0.70 V. On the analogy of the metal oxide growth, the observed rapid and linear growth of DyNi₂ films may be explained by the existence of the outer and inner DyNi₂ layers.

Electron transport in InGaO3(ZnO)m (m=integer) studied using single-crystalline thin films and transparent MISFETs

We have investigated the characteristics of transparent metal-insulator-semiconductor field-effect transistors (MISFETs) fabricated using InGaO₃(ZnO)_m (m=integer) single-crystalline thin films as n-channel layers and amorphous alumina as gate insulator films. The MISFETs exhibit good characteristics such as insensitivity to visible light illumination, off-current as low as ∼1 nA with a positive threshold voltage of ∼3 V and on/off current ratio of 10⁵. The field-effect mobility increased from ∼1 to ∼10 cm² (V s)⁻¹ as the m-value increased. Room temperature Hall mobility also increased. However, unexpectedly these values were lower than the field-effect mobility. It is explained by existence of shallow localized state in the homologous compounds.
