Contact resistance in organic transistors that use source and drain electrodes formed by soft contact lamination
Soft contact lamination of source/drain electrodes supported by gold-coated high-resolution rubber stamps against organic semiconductor films can yield high-performance organic transistors. This article presents a detailed study of the electrical properties of these devices, with an emphasis on the nature of the laminated contacts with the pand n-type semiconductors pentacene and copper hexadec...
متن کاملMinimizing electrode edge in organic transistors with ultrathin reduced graphene oxide for improving charge injection efficiency.
Electrode materials and geometry play a crucial role in the charge injection efficiency in organic transistors. Reduced graphene oxide (RGO) electrodes show good compatibility with an organic semiconductor from the standpoint of energy levels and ordered growth of the organic semiconductor, both of which are favourable for charge injection. However, the wide electrode edge (>10 nm) in commonly-...
متن کاملImproving charge injection in organic thin-film transistors with thiol-based self-assembled monolayers
The aim of this work is to improve charge injection by interposing an appropriately oriented dipole layer between contact and semiconductor in organic thin-film transistors (OTFTs). OTFTs are fabricated with pentacene semiconductor and gold source and drain contacts. The contacts are modified with self-assembled monolayers (SAMs) made of alkane or fluorinated alkane thiols. Ultraviolet photoele...
متن کاملParasitic resistance in bottom-contact pentacene thin-film transistors that use water- dispersible polyaniline electrodes
Introduction Organic thin-film transistors (TFT) have received considerable attention due to promises of low manufacturing costs, ease of processibility, and extendibility to flexible circuits. The feasibility of organic TFTs has largely been demonstrated with devices that use metal source and drain electrodes, such as gold and palladium. Such devices, when fabricated in the bottom-contact (BC)...
متن کاملThickness dependence of mobility of pentacene planar bottom-contact organic thin-film transistors
We have fabricated planar bottom-contact organic thin-film transistors as a function of the thickness of the pentacene active layer. The highest mobility of the planar bottom-contact transistors is 0.47 cm/Vs with only a 7 nm pentacene active layer. Our planar bottom-contact transistors show much higher mobility than conventional bottom-contact counterparts and even higher than the reported mob...
