Ag/TCNQ双层膜传质规律与模型的理论研究

有机分子结构的多样性以及独特的光学、电学和磁学性质已引起了人们的高度重视，功能有机薄膜的深入研究已有报道，这些研究大多涉及金属／有机复合薄膜，因此研究金属／有机物双层膜间的传质过程已成为一个重要的科研课题，这对特殊结构膜的制备、可控纳米结构的实现、膜结构的稳定性及薄膜的应用与失效分析具有重要的科学与实际意义。

Theoretical Studies on Transport Behavior and Model of Ag/TCNQ Double-layer Thin Film

Ag/TCNQ double-layer films with different thicknesses were prepared on glasses substrate by alternately vacuum deposition of Ag and TCNQ. The metal-organic complex Ag-TCNQ formed through transport at room temperature and in atmosphere environment. The transport behavior in the film was studied by using transmission spectrum to monitor the process. An abnormal accelerated transport phenomenon was observed with the decrease of the thickness of the film, which was different from the parabola law between transport distance and transport time when the film was thicker. Tunneling and non-tunneling models were established respectively based on whether the tunneling condition was met. The theoretical analyses were carried out in detail.
