Layer-by-layer assembled 2D montmorillonite nanosheets are shown to be high-performance, solution-processed dielectrics. These scalable and spatially uniform sub-10 nm thick dielectrics yield high areal capacitances of ≈600 nF cm(-2) and low leakage currents down to 6 × 10(-9) A cm(-2) that enable low voltage operation of p-type semiconducting single-walled carbon nanotube and n-type indium gallium zinc oxide field-effect transistors.
层层组装的二维蒙脱石纳米片被证明是高性能的溶液处理电介质。这些可扩展且空间均匀的亚 10nm 厚电介质具有约 600nFcm(-2)的高面电容和低至 6×10(-9)Acm(-2)的泄漏电流，可实现 p 型半导体单壁碳纳米管和 n 型铟镓锌氧化物场效应晶体管的低压操作。
