This paper presents both analytical modeling and simulations based on finite element method of Pentacene Thin Film Transistors or Organic Thin Film transistors (PTFTs/OTFTs). Analytical modeling approach is introduced by using conventional transistor equations and finite element method using ATLAS two dimensional numerical device simulators. Both the methods shows a good agreement of output cha...

The demand of cost-effective fabrication printed flexible transistors has dramatically increased in recent years due to the need for interface devices various application including e-skins, wearables, and medical patches. In this study, electrohydrodynamic (EHD) printing processes are developed fabricate all components polymer-based organic thin film (OTFTs), source/drain gate electrodes, semic...

Thin film transistor circuits using organic semiconductors (oTFT) have received intense interest for applications requiring structural flexibility, large area coverage, low temperature processing, and low-cost [1]. Pentacene TFTs have demonstrated the highest performance among TFTs with an organic semiconductor channel. A major limitation, however, has been unusually high operating voltages (20...

Organic thin-film transistors (OTFT) present a new approach to building electronics that can mechanically flex, span large areas, and integrate with polymeric materials. Potential applications include flexible displays, biochemical sensors, and artificial skin. In many applications, OTFTs act as an interface between the physical environment and the digital processors. Yet, a conspicuous absence...

The general form of interfacial contact resistance was derived for organic thin-film transistors (OTFTs) covering various injection mechanisms. Devices with a broad range of materials for contacts, semiconductors, and dielectrics were investigated and the charge injections in staggered OTFTs was found to universally follow the proposed form in the diffusion-limited case, which is signified by t...

The surface functionalization by self-assembled monolayers (SAMs) favors well-packed organic semiconductor growth and reduces interfacial traps, which assists in developing high-performance thin-film transistors (OTFTs). Herein, the conventional SAM from vapor phase is ameliorated systematically studied. With 1H,1H,2H,2H-Perfluorodecyltrichlorosilane as an example, it found that deposition temp...
