Molecular orientation transition of organic thin films on graphite: the effect of intermolecular electrostatic and interfacial dispersion forces.
In situ low-temperature scanning tunnelling microscopy investigation reveals a molecular orientation transition of organic thin films of pentacene and p-sexiphenyl on graphite, arising from the delicate balance between the intermolecular electrostatic and interfacial dispersion forces.
