作者表明，由标题金属有机电荷转移盐（四硫富瓦烯）（四氰基醌二甲烷）[（TTF）（TCNQ）]制成的源极和漏极导致有机薄膜晶体管（TFT）的接触电阻急剧降低。采用变栅长传输线法估算接触电阻。与底部接触Au晶体管相比，具有有机电极的并五苯TFT显示出更小的接触电阻和更大的总迁移率，其数量级超过一个。其性能与顶接触Au晶体管相当，表明（TTF）（TCNQ）是用于底接触晶体管的优良电极材料。
The authors show that source and drain electrodes made of the title metallic organic charge-transfer salt (tetrathiafulvalene)(tetracyanoquinodimethane) [(TTF)(TCNQ)] result in drastic reduction of contact resistance in organic thin-film transistors (TFTs). The contact resistance is estimated by the variable gate-length transfer-line method. Pentacene TFTs with the organic electrodes show smaller contact resistance and larger overall mobility by more than one order than those of bottom-contact Au transistors. The performance is comparable to that of top-contact Au transistors, indicating that (TTF)(TCNQ) is an excellent electrode material for bottom-contact transistors.
