摘要: 以高掺杂Si单晶片作为栅电极,热生长SiO_2作为栅介质层,聚三己基噻吩薄膜作为半导体活性层,Au作为源、漏电极,并采用十八烷基三氯硅烷(OTS)对栅介质表面改性,在空气环境下成功地制备出高性能聚合物薄膜晶体管.结果表明,通过采用OTS对栅介质层表面修饰大幅度地改善了聚合物薄膜晶体管的电性能,器件的场效应迁移率高达0.02 cm~2,(Vs),开关电流比大于10~5.Abstract: Polymer-based thin film transistors (PTFTs) were successfully fabricated on silicon substrates which was used as gate electrode, thermal silicon dioxide was used as gate insulators and poly(3-hexylthiophene) as semiconducting active layers for the transistors. The fabrication and measurement of the devices were all performed in the clean air. The PTFTs with a surface modified gate insulator show better electric characteristics with the field-effect mobility of 0.02 cm~2//(Vs) and the on/off ratio higher than 10~5 .
