Abstract

Studying highly energetic pentacene impinging on a surface, we demonstrated that the perpendicular component of the momentum drives the dynamics of molecule-molecule interactions and hence the island nucleation process, while the parallel component governs the dynamics of the interactions between the surface and the molecule and therefore determines the sticking coefficient and the island fractality.

摘要

通过研究高能并五苯撞击表面的情况，我们证明了动量的垂直分量驱动分子间相互作用的动力学，进而驱动岛状核形成过程，而平行分量则控制表面与分子间相互作用的动力学，因此决定了附着系数和岛状分形性。
