Organic Semiconductors
One of the most exciting opportunities in electronics, optoelectronics or flexible
electronics is to be able to make devices based on organic semiconductors. Organic
active materials can exhibit many advantages such as lower demands on processing
technology with less sensitivity to the processing environment, flexibility, and the
opportunity to apply the simplicity of organic synthesis to tailoring the properties of
the materials for specific applications [1].
Depending on their vapor pressure and solubility, organic semiconductors are
deposited either from a vapor or solution phase. In this section, some of the organic
semiconductor deposition methods are discussed.
Similar to its inorganic counterparts, organic semiconductors have been the subject
of extensive research to produce organic electronic devices such as organic
photovoltaic cells (OPV), organic field-effect transistors (OFET), and organic lightemitting
diodes (OLED) [2, 3, 73–77, 82]. However, organic semiconductors have
certain limitations such as a short lifetime, degradation byUVlight, temperature sensitivity,
low efficiency compared to inorganic semiconductors, and not well understood
charge transfer mechanisms. Despite these limitations, advantages like their
lightweight, transparency, flexibility, and lower production cost make them candidates
for the development of novel electronic devices fomenting research in this
area. It is worthwhile to note that organic semiconductors have been combined
with other carbon nanomaterials like carbon nanotubes, fullerenes, and graphene,
to improve their charge carrier mobility, which is one of the limitations of polymers
and oligomers
