Using the density functional theory combined with the effective screening medium method, the dynamical properties of a Ne atom near graphene edges under an external electric field are investigated. The field-induced motions of a Ne atom near the graphene edges are sensitive to the initial position of Ne and the edge morphology of graphene. The Ne atom is attracted to the edge atomic sites of graphene when it is initially located above the edges. The Ne atom moves to the counter negative electrode when it is located alongside the armchair edge. The Ne atom approximately maintains its initial position when it is located alongside the zigzag edge owing to the polarity of the Ne atom induced by the edge morphology.

使用密度泛函理论结合有效屏蔽介质方法，研究了外电场作用下石墨烯边缘附近Ne原子的动力学性质。石墨烯边缘附近的 Ne 原子的场致运动对 Ne 的初始位置和石墨烯的边缘形态敏感。当 Ne 原子最初位于边缘上方时，它会被吸引到石墨烯的边缘原子位点。当 Ne 原子位于扶手椅边缘时，它会移动到反负电极。由于边缘形态诱导的 Ne 原子的极性，当它位于锯齿形边缘旁边时，Ne 原子大致保持其初始位置。
