Title: Monolayer and Bilayer Perfluoropentacene on Cu(111)

Journal Article · · Journal of Physical Chemistry. C

Perfluoropentacene (PFP), an n-type organic semiconductor, is deposited at monolayer and bilayer coverages on Cu(111). Scanning tunneling microscopy at various bias voltages is used to investigate the geometric and electronic structures of the layer. The appearances of the first layer and second layer differ, likely due to perturbation of the first layer electronic structure by the substrate. This has been previously observed for pentacene (Pn), the isostructural p-type organic semiconductor. The PFP film has a unit cell of (4, -3,3 4) relative to the substrate, which is larger than that of Pn/Cu(111), representing a half-integer increment in each direction.
