【摘要】：通过对OTFT绝缘层SiO_2表面分别采用十八烷基三氯硅烷(OTS)处理和原子层沉积薄层氧化铝的修饰方式,制备了喷墨打印有机薄膜晶体管并研究了修饰前后绝缘层的表面形貌、接触角及有源层的物相结构。虽然绝缘层的表面形貌在修饰前后变化不大,但是表面接触角和打印后有源层的物相结构有较大差别。OTS处理和沉积氧化铝修饰后,器件的迁移率比修饰前分别增大了4倍和9倍,而开关比则分别增大了1个和4个数量级。修饰后的最大迁移率可达0.35 cm~2/(V·s),开关比可达6.0×10~6。
[Abstract]:Based on the OTFT insulation layer SiO_2 surface by using eighteen three alkyl chlorosilane (OTS) and atomic layer deposition of thin layer of alumina was prepared by modified method, inkjet printing organic thin film transistor and to study the morphology of the surface of the insulation layer before and after modification, the contact angle and the active layer structure. Although little change in surface morphology of insulating layer in the modification, but the surface contact angle and printed active layer phase structure has a larger difference between.OTS treatment and deposition of alumina modified device mobility than unmodified increased respectively 4 times and 9 times, while the switch ratio is increased respectively 1 and 4 orders of magnitude. The modified maximum the migration rate of up to 0.35 cm~2/ (V - s), the switch ratio can reach 6 * 10~6.
