摘要:

石墨烯场效应晶体管与溶液处理的多层混合有机-无机自组装纳米电介质(SAND)集成。与传统SiO2栅压控制器件相比,所得到的器件具有低工作电压(2 V)、可忽略的滞后、在真空(压力< 2 x 10-5 Torr)中具有> 1.0的本征增益的电流饱和以及整体性能的改善。场效应迁移率和残余载流子浓度的统计分析表明,在整个3英寸晶片上的电介质界面性质和石墨烯晶体管特性的高度空间均匀性。因此,这项工作确立了SAND作为大面积,高性能石墨烯电子产品的有效平台。

英文摘要:

Graphene field-effect transistors are integrated with solution-processed multilayer hybrid organic-inorganic self-assembled nanodielectrics (SANDs). The resulting devices exhibit low-operating voltage (2 V), negligible hysteresis, current saturation with intrinsic gain > 1.0 in vacuum (pressure < 2 x 10-5 Torr), and overall improved performance compared to control devices on conventional SiO2 gate dielectrics. Statistical analysis of the field-effect mobility and residual carrier concentration demonstrate high spatial uniformity of the dielectric interfacial properties and graphene transistor characteristics over full 3 inch wafers. This work thus establishes SANDs as an effective platform for large-area, high-performance graphene electronics.
