标题： High-performance planar nanoscale dielectric capacitors

摘要： 我们提出了一种平面纳米尺度的电介质电容器模型，该模型由单层绝缘六边形氮化硼（BN）条带组成，位于两个金属石墨烯条带之间，所有部分共同形成一个单一的原子平面。 对于不同充电水平和不同宽度的石墨烯-BN条带的这些纳米尺度电容器进行的第一性原理密度泛函计算表明，其质量比电容值较高，与由其他碳基材料制成的超级电容器相当。 目前的纳米电容器模型允许制造串联、并联和混合组合，这在二维柔性纳米电子学、能量存储和热压传感系统中具有潜在应用。 显示英文摘要

摘要： We propose a model for planar nanoscale dielectric capacitor consisting of a single layer, insulating hexagonal boron nitride (BN) stripe placed between two metallic graphene stripes, all forming commensurately a single atomic plane. First-principles density functional calculations on these nanoscale capacitors for different levels of charging and different widths of graphene - BN stripes mark high gravimetric capacitance values, which are comparable to those of supercapacitors made from other carbon based materials. Present nanocapacitor model allows the fabrication of series, parallel and mixed combinations which offer potential applications in 2D flexible nanoelectronics, energy storage and heat-pressure sensing systems.
