Abstract

Bottom- and top-contact organic thin film transistors (OTFTs) were fabricated, using poly(3-hexylthiophene-2,5-diyl) (P3HT) and poly[2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene] (PBTTT-C16) as p-type channel semiconductors. Four different types of OTFTs were fabricated and investigated as gas sensors against three volatile organic compounds, with different associated dipole moments. The OTFT-based sensor responses were evaluated with static and transient current measurements. A comparison between the different architectures and the relative organic semiconductor was made.

摘要

利用聚（3-己基噻吩-2,5-二亚基）（P3HT）和聚[2,5-双（3-十四烷基噻吩-2-基）噻吩并[3,2-b]噻吩]（PBTTT-C16）作为p型沟道半导体，制备了底部和顶部接触的有机薄膜晶体管（OTFT）。制备了四种不同类型的OTFT，并将其作为针对三种具有不同相关偶极矩的挥发性有机化合物的气体传感器进行研究。基于OTFT的传感器响应通过静态和瞬态电流测量进行评估。对不同结构和相关有机半导体进行了比较。
