16206 以p型共轭有机小分子2,7二辛基[1]苯并噻吩并[3,2-b]苯并噻吩(C8-BTBT)作为底栅顶接触有机薄膜晶体管(OTFT)的有源层,采用浸渍提拉法、喷墨打印法和真空蒸镀法三种制备工艺,探究半导体薄膜载流子迁移率与结晶形貌的关系,发现不同工艺下有机;小分子呈现出不同的生长行为和结晶情况,在很大程度上决定了OTFT器件性能的优劣。 In order to investigate the relationship between carrier mobility and crystal morphology of semiconductor thin films,the p-type conjugated organic small molecule 2,7 dioctyl[1]benzothieno[3,2-b][1]benzothiophene(C8-BTBT)was adopted as the active layer of bottom-gate top-contact organic thin film transistor(OTFT),three kinds of processes,and dip-coating,ink-jet printing and vacuum evaporation,were used to prepare the C8-BTBT film. The growth behavior and crystallization of small organic molecules and their effects on the properties of OTFT devices varied with different processes.

16208 结果表明,真空蒸镀制备的薄膜具有更高的结晶度、衬底覆盖率高,并且呈现出SK(Stranski-Krastanov)模式的结晶生长特征,相应器件中陷阱密度最低,迁移率高达5.44 cm2·V-1·s-1,开关比超过106。 The results show that the films deposited by evaporation have higher crystallinity,high substrate coverage,and exhibit the Stranski-Krastanov(SK)growth mode,and the trap density of the corresponding device is the lowest,so that the mobility is as high as 5.44 cm2·V-1·s-1 and the on/off is more than 106.
16209 且退火处理会严重破坏C8-BTBT薄膜的结晶。 In addition, annealing could severely destroy the crystallization of C8-BTBT.
16210 因此,控制半导体层的生长行为,提升半导体层的覆盖率和结晶度是制备高性能共轭小分子OTFT器件的有效途径。 Therefore, controlling the growth behavior of the semiconductor layer,therefore improving the coverage and crystallinity of the semiconductor layer is an effective way to fabricate high performance conjugated small molecule OTFT devices.
