Graphene is a one-atom thick
carbon sheet with exceptional properties. Tuning
its electronic structure is important for carbon
based electronics.
Organic Solid-Solid Wetting Deposition (
OSWD) enables to
adsorb insoluble organic semiconductors and
pigments on various substrates. The list of
suitable substrates include graphene and carbon
nanotubes. We thus investigate possible
OSWD-induced chemical doping effects of
single-layer graphene.
According to our results, based on different
spectroscopic methods, OSWD enables
surface-transfer doping of graphene. The results
open up a very easily applicable, low-cost, and
eco-friendly way for bandgap engineering of
graphene via commercially available organic
pigments.
