Growth dynamics in supersonic molecular beam deposition of pentacene sub-monolayers on SiO2

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. © 2014 The Royal Society of Chemistry.
