Molecular orientation, crystallite size and lattice disorders in organic semiconductor (OSC) thin films determine the transport of electrons or excitons in the OSC thin films, and thus the performance of organic or graphene-OSC hybrid electronic devices. It has been shown that the control of the properties of OSC thin films can be achieved by using graphene as a growth template because the interaction between OSC molecules and graphene affects the molecular orientation and diffusivity of the OSC molecules on graphene. In this talk, the assembly mechanism of OSC molecules on graphene template will be discussed. In particular, the effects of various factors, such as surface contamination, doping, and roughness of graphene template, on the growth OSC thin films will be discussed. Lastly, I will present the application of the OSC thin films grown on graphene template in high-performance organic thin film transistors, organic photovoltaics, and graphene-OSC hybrid electronic devices. |
