ABSTRACT
Organic thin-film transistors (OTFTs) employing a flexible, conductive carbon particle-polymer composite material for the drain-source ohmic contacts are reported herein. The contacts can be deposited using standard stencil printing techniques and are processed at low temperature, thereby facilitating their integration with heat sensitive substrates. The carbon contacts were stencil printed on a silicon dioxide gate dielectric layer, and the poly(3-hexylthiophene) semiconductor was deposited via solution casting from toluene. The OTFTs exhibited field-effect behavior over a range of drain-source and gate voltages, similar to devices employing deposited gold contacts. © 2003 American Institute of Physics.

    Field effect transistors require an Ohmic source contact and an Ohmic drain contact for ideal operation. In many real situations, however, and specifically in organic devices, the injection of charge carriers from metals into semiconductors can be an inefficient process that is non-Ohmic. This...

    Al/glass specimens are prepared following the orthogonal table of five-level six-factorial (L(5)) design. The governing factors for the preparation of the specimens are deposition conditions, annealing temperature and annealing time. Defects, including hillocks and nanovoids, are found to be...
