Feasibility of solution processed organic field-effect transistors

Abstract : Present work deals with the new trend to get highly flexible electronics by using fully Organic Thin-Film Transistor (OTFT) as the basic element of this electronics. Fully organic n-type as well as p-type OTFT processed by inkjet printing are studied. Printing parameters of each ink, jettability, wetting, printability, and patterns optimization, leading to the deposition of conductive contacts, gate insulator and semiconducting active layer are studied. Process of n-type OTFT based on C60 is shown as unreliable, mainly due to the poor solubility of C60 in organic solvent. In the contrary, p-type OTFTs based on Tips-pentacene are much more reliable. The work is a large overview of the issues and the difficulties that have been to jump and to solve in the way to fabricate fully printed organic transistors. Some solutions have been given and new ideas have been proposed.
