摘　　要：采用真空热蒸发方法在玻璃基板上蒸镀不同厚度的Ag/TCNQ(7,7,8,8_tetracyanoquinodimethane)双层膜.通过固体化学反应扩散,最终形成Ag_TCNQ络合物.利用透射光谱表征,研究了双层膜中的传质规律.按电子隧穿条件满足与否分别建立了隧穿模型和非隧穿模型对体系传质过程进行了理论分析,理论分析与实验结果相符.Ag/TCNQ （7,7,8,8-tetracyanoquinodimethane） bi-layer films with different thickness were prepared by physical vapor deposition method. The metal-organic complex Ag-TCNQ is formed through transport. The transport behavior in the film was studied using transmission spectrum to monitor the process. Tunneling model and non-tunneling model were established respectively based on whether the tunneling condition was met. Theoretical analysis was carried out in detail. The results of our theoretical models are in good agreement with the experiment data.
