基于蛋清栅绝缘层的高性能C60有机场效应晶体管

摘要

采用生物材料(蛋清)作为栅绝缘层制备了基于 C60为有源层的有机场效应晶体管。器件展现出了合理的电学特性，场效应迁移率和阈值电压分别为2.59 cm2·V -1·s -1和1.25 V。有机场效应晶体管展现良好性能的原因是蛋清具有较高的介电常数及热退火后形成的光滑表面形貌。实验结果表明，对于制备有机场效应晶体管来说，蛋清是一种有前途的绝缘层材料。%We fabricate C60-based organic field-effect transistors (OFETs) with a biomaterial (albu-men) as the gate dielectrics. The devices demonstrate reasonable electrical characteristics. The ef-fective field-effect mobility is 2. 59 cm2 ·V - 1 ·s - 1 , and the threshold voltage is 1. 25 V. The en-hanced performances of the OFETs are attributed to the high dielectric constant, smooth surface after the appropriate thermal treatment of the albumen dielectric. The experiments show that albumen is a promising dielectric material for OFETs.
