      A prospect of flexible electronics lines with the development of functional devices based on disordered semiconductors, such as organic and soluble inorganic materials. Flexible optoelectronic applications need a wide variety of electronic components of photovoltaics (PVs), organic light emitting diodes (OLEDs) and field effect transistors (FETs). Those devices are basically composed of two- or three-terminal contacts which have the interfaces of metal/semiconductor (SC), dielectric/SC and SC/SC. Thus, the interfacial engineering is predominant to realize those devices for flexible application. A crucial issue concerning charge injection at the interface of electrode/organic semiconductor is recently rising in order to improve the electrical performance of diodes and FETs. This presentation gives an investigation on charge injection via the modification of electrodes with self assembled monolayers (SAMs) in organic electronic devices. Functionalized SAMs with fluorine at the end group plays a substantial role to improve charge injection through a dipolar effect to decrease barrier height at the electrode/semiconductor interface in a planar diode and organic field effect transistors (OFETs). This is extended to significant enhancement of electrical performance such as field effect mobility and contact resistance in OFET.
