Analytic model for organic thin film transistors (OTFTs): effect of contact resistances application to the octithiophene

The European Physical Journal Applied Physics, 2009
Thin film organic field-effect transistors were grown with vapor-deposited polycrystalline-octithiophene on silicon oxide insulating layers. This component requires an ohmic source and drain contacts for ideal operation. The performance of organic electronic-devices is often limited by injection.

Functionalized benzothieno[3,2 b]thiophenes (BTTs) for high performance organic thin-film transistors (OTFTs)

Journal of Materials Chemistry C, 2014
New benzothieno[3,2-b]thiophene (BTT) derivatives, end-functionalized with biphenyl (Bp-BTT), naphthalenyl (Np-BTT), and benzothieno[3,2-b]thiophenyl (BBTT; dimer of BTT) moieties, were synthesized and characterized for bottom-gate/top-contact organic thin-film transistors (OTFTs). All three materials exhibit good environmental stability as assessed by

Enhanced Ammonia (NH3) Sensing Response of UV-Light Treated Organic Thin-Film Transistors(OTFTs)

ECS Transactions, 2008
Pentacene thin-film transistors have great potential because of low cost, large-area circuits, and relatively high mobility. Due to active organic layers, OTFTs have suitable analyte response properties with high sensitivity in both gaseous(1) and aqueous(2) environments.

Application of tosylate-doped poly(3,4ethylenedioxythiophene) (PEDOT) films into bottom contact pentacene organic thin film transistors (OTFTs)

Thin Solid Films, 2010
Abstract The effect of iron(III) p-toluenesulfonate hexahydrate (Fe(PTS)3) concentration on the formation and patternability of poly(3,4ethylenedioxythiophene) (PEDOT) films on (3-aminopropyl)trimethoxysilane (APS) monolayer was investigated. Low deposition rate yielded highly conductive and very smooth PEDOT films.

CHEMICAL MODIFICATION OF GATE DIELECTRIC SURFACES IN ORGANIC THIN FILM TRANSISTOR (OTFT) THROUGH MOLECULAR SELF-ASSEMBLY

Molecular Crystals and Liquid Crystals, 2003
To modify SiO 2 dielectric surface of bottom-contact OTFT device, octadecyl-triethoxysilane (OTES) was used to find optimum condition of surface modification for triethoxysilane derivatives. Either spin-coating method or solution dipping method was applied to modify the dielectric surface with OTES.

Investigation of Variation in Organic Thin-film Transistors (OTFT) and Design of Variation-aware Organic Circuits

2016
This work investigates the key sources of variability in OTFT namely process variations and bias-stress induced variation, and presents circuit design techniques to build robust variation-aware digital and analog circuits using OTFT. OTFT suffer from a relatively large Vt variation due to the bias stress effects, and process mismatch variations. Though

Low-k polymer gate dielectric selection for organic thin-film transistors (OTFTs) using material selection methodologies

Journal of Computational Electronics, 2019
Performance parameters of an organic thin-film transistor (OTFT) and their relation to the material parameters of the gate dielectric are analyzed. Based on the analysis, the surface energy, dielectric constant, glass-transition temperature, and breakdown field are identified as key parameters.
