Abstract:
Conventional electronics rely on inorganic semiconductors viz., silicon,
germanium, III-V compounds and oxide dielectrics. The device physics and
mechanisms. of charge transport in these materials are well understood. However, there
has been a quest for new materials which offer other advantages such as mechanical
strength, large optical window and ease of processability. The discovery of high
electrical conductivity in polyacetylene by Shirakawa, Mcdiarmid, and Heeger in the
seventies witnessed a surging interest in the research and development of conjugated
polymer materials and devices associated with it.[1] Many forms of organic electronic
materials with high performance and stability have emerged since then.[2] Three primary
devices: organic light emitting diodes (OLEDs), organic photovoltaics (OPVs) and
organic field effect transistors (OFETs) have set the pace of activities in the last two
decades in this field which has enabled Organic electronics-based devices increasingly
find their place in the commercial space.
