Different Work Regimes of an Organic Thin Film Transistor OTFT and Possible Applications in Bioelectronics [PDF]

American Journal of Bioscience and Bioengineering, 2015
This paper presents an organic semiconductor transistor, with a vertical current modulation and a horizontal conduction. The simulations show a stronger top gate influence and establish four work regimes, depending on the top and bottom gates biasing. In the most favorable regime for the holes channel, under the reverse biased n+p junction, the holes ...

Fabrication of Organic Thin Film Transistor(OTFT) Array by Using Nanoprinting Process

Key Engineering Materials, 2006
The flexible organic thin film transistor(OTFT) array to use as a switching device for an organic light emitting diode(OLED) was designed and fabricated in the nanocontact printing and low-temperature process. The gate, source, and drain electrode patterns of OTFT were fabricated by nanocontact printing process.

THM-OTFT: A Complete Physics-Based Verilog-A Compact Model for Short-Channel Organic Thin-Film Transistors [PDF]

IEEE Journal of the Electron Devices Society, 2023
This paper presents a compact model for organic thin-film transistors fabricated in the staggered or coplanar device architecture which includes short-channel effects related to the potential barrier in the channel region, which manifest themselves as threshold voltage roll-off, drain-induced barrier lowering, and subthreshold swing degradation ...

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

, 2015
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

Investigation of gate dielectric interface on contact resistance of short channel organic thin film transistors (OTFT)

PLOS One
This study provides a comprehensive analysis of the impact of the interfacial properties on the performance of organic thin-film transistors (OTFTs) with a hybrid dielectric of Al2O3/PVP compared to single-layer dielectrics of Al2O3 and PVP. The analyses were performed using the 2D Silvaco Atlas numerical simulator, which conducted a detailed numerical

An Organic Thin-Film Transistors (OTFTs) With Steep Subthreshold and Ultra-Low Temperature Solution Processing for Label-Free Biosensing

IEEE Access
In this study, we propose a novel dielectric modulated dual-dielectric bottom-gate top-contact organic thin film transistor (DMDDBG-OTFT) as a label-free biosensor for detecting neutral and charged bio-analytes. The device utilizes PVP and Al2O3 as dual-dielectric layers, offering superior sensitivity, selectivity, low leakage current, and low ...

Synthesis and Characterization of Benzodithiophene (BDT) Quinoid Compounds as a Potential Compound for n-Type Organic Thin-Film Transistors (OTFT)

Jurnal Kimia Sains dan Aplikasi, 2020
Two potential compounds as an n-Type organic thin-film transistor (OTFT) from benzodithiophene (BDT) derivatives have been synthesized and characterized. BDT was chosen as the core because it has π-conjugated bonds, rigid structures, and planar. Quinoid structure with end-cap (terminal group) in the form of dicyanomethylene is used because it can lower
