摘要： 本文采用内部电极、电容耦合式钟罩型射频等离子体聚合装置,首次进行了四氰代对二次甲基苯醌(TCNQ)的等离子体聚合,得到了电导率为10-8～10-6Scm-1的聚合物半导体薄膜。由这些聚合物薄膜制备的Al/聚合膜/ITO(铟锡氧化物透明电极)夹层元件显示出整流特性和光生伏打效应。这种聚合物薄膜还具有光电导性质。红外光谱(IR)、紫外光谱(UV)的研究结果表明,优良的半导体特性归因于聚合膜中存在有较大范围的π电子共轭结构。

Abstract: Plasma polymerization of TCNQ(tetracyanoquinodimethane) was carried out by using acapacitively coupled radio-frequency bell jar apparatus with internal electrodes.Some semi-conductive polymeric films with conductivities ranged from 10-8 to 10-6.Scm-1 were ob-tained.The Al/polymeric film/ITO (indium tin oxide) sandwich cells made of the filmsshowed rectifying behavior and photovoltaic response.Photoconductivity was also observedwith the films.The infrared and ultraviolet spectroscopic results showed that the goodsemiconductive properties are due to the more extended conjugated structure in the films.

Key words: TCNQ, plasma polymerization, semiconductive film, retifying behavior, photovoltaic effect, photoconductivity
