Precise Structure of Pentacene Monolayers on Amorphous Silicon Oxide and Relation to Charge Transport

Authors


Abstract

The precise molecular packing in pentacene monolayers on silicon oxide is determined for the first time using a combination of grazing incidence X-ray diffraction (GIXD) and crystallographic refinement calculations. The pentacene molecules are found to adopt a completely tilt-free herringbone motif, the charge-transport properties of which are discussed on the basis of density functional theory calculations.
