论文摘要
在这项工作中，证明了具有低电容的金属 - 胰蛋白二极管（1D-mig）二极管的新型一维几何形状。 1D-MIG二极管的连接在用作屏障材料的TiO2的Al2O3封装石墨烯的1D边缘形成。二极管表现出自石墨烯中的运输和通过屏障的运输以来的超高电流密度。几何形状在二极管的阴极和阳极之间提供了非常低的电容耦合，该二极管显示频率响应高达100 GHz，并确保潜在的高频性能高达2.4 THz。证明1D-MIG二极管在柔性底物上的弯曲条件下低于6.4 mm弯曲半径下均匀和稳定。
In this work, a novel one-dimensional geometry for metal-insulator-graphene (1D-MIG) diode with low capacitance is demonstrated. The junction of the 1D-MIG diode is formed at the 1D edge of Al2O3-encapsulated graphene with TiO2 that acts as barrier material. The diodes demonstrate ultra-high current density since the transport in the graphene and through the barrier is in plane. The geometry delivers very low capacitive coupling between the cathode and anode of the diode, which shows frequency response up to 100 GHz and ensures potential high frequency performance up to 2.4 THz. The 1D-MIG diodes are demonstrated to function uniformly and stable under bending conditions down to 6.4 mm bending radius on flexible substrate.
