| 摘 要： | 采用六联苯(p-6P)和氧钒酞菁(VOPc)作为有源层材料,利用弱外延生长技术制备有机薄膜晶体管(OTFT)。在相同的工艺条件下制备了顶栅结构(top-gate)和底栅结构(bottom-gate)两种器件构型,发现两种不同结构的OTFT器件特性存在较大的差异,top-gate OTFT的迁移率比bottom-gate OTFT高很多。在顶栅结构的器件构型中获得了较高的器件特性参数,迁移率达到1.6cm2/V.s。研究了弱外延生长技术应用在两种不同器件构型中的差异,并解释了顶栅结构OTFT迁移率较高的原因。

| Abstract: | Organic thin film transistors based on Weak Epitaxy Growth(WEG) technology are fabricated with two different design: top-gate and bottom-gate configurations.The active layer materials of the OTFT are p-6P and vanadyl phthalocyanine(VOPc).The two structural OTFTs are prepared under the same process conditions,and it is found that the device performance is different.The mobility of top-gate OTFT is much higher than that of the bottom-gate OTFT.A high mobility of 1.6 cm2/V·s is obtained in the top-gate structure.The differentiation of top-gate and bottom-gate OTFTs is studied by Weak Epitaxy Growth(WEG) technology,and the reasons of higher mobility OTFT based on the top-gate configuration is explained. |
