In situ–Directed Growth of Organic Nanofibers and Nanoflakes: Electrical and Morphological Properties

Abstract

Organic nanostructures made from organic
molecules such as para-hexaphenylene (p-6P) could form
nanoscale components in future electronic and optoelectronic
devices. However, the integration of such fragile
nanostructures with the necessary interface circuitry such
as metal electrodes for electrical connection continues to be
a significant hindrance toward their large-scale implementation.
Here, we demonstrate in situ–directed growth of
such organic nanostructures between pre-fabricated contacts,
which are source–drain gold electrodes on a transistor
platform (bottom-gate) on silicon dioxide patterned by a
combination of optical lithography and electron beam
lithography. The dimensions of the gold electrodes strongly
influence the morphology of the resulting structures leading
to notably different electrical properties. The ability to
control such nanofiber or nanoflake growth opens the
possibility for large-scale optoelectronic device fabrication.
