Quantum dots: A sequential, single-electron charging process of monodisperse graphene quantum dots (GQDs) encapsulated in a dodecylamine envelope, facilitating a capacitance of a few attofarads is reported. The average GQDs dimensions, as ascertained from high-resolution transmission electron microscopy and atomic force microscopy, of about 3±0.3, 2.6±0.2, and 2.2±0.3 nm control this unprecedented behavior.
在十二胺包封的单分散石墨烯量子点（GQDs）中，报告了一个连续的单电子充电过程，其电容约为几个飞法拉。从高分辨率透射电子显微镜和原子力显微镜确定的平均 GQDs 尺寸约为 3±0.3、2.6±0.2 和 2.2±0.3nm，控制着这种前所未有的行为。
